TA5704EVM 4-Channel Digital Audio Power Amplifier with
Hardware Control
1
Overview
TAS5704 customer evaluation module (EVM) demonstrates the integrated circuit (IC) TAS5704 from
Texas Instruments (TI).
TAS5704 is a 4-channel device with an I2S/RJ/LJ digital audio stream input and amplified PWM signal
out. The subwoofer PWM signal is provided to an external class D power stage (TAS5601), which uses a
LC demodulation filter to drive a subwoofer. For detail information about the TAS5704 device review the
device data sheet, document number SLOS563.
TAS5704 is designed to drive two 8-Ω loudspeakers up to 20W per channel (10%THD+N) in a BTL
configuration. The TAS5704EVM can also be configured to drive four, 4-Ω speakers in a single-ended
(SE) configuration. Finally, the TAS5704EVM can be configured to drive 2 single-ended speakers plus 1
bridge-tied speaker (2.1 mode). Review the board schematic, and TAS5601 documents for additional
information and more specific application information on the subwoofer daughter card and connector.
TAS5704EVM, together with other TI components on this board, is a complete 4 channel digital audio
amplifier system, which includes digital input (SPDIF), analog inputs via ADC, and other features like
mute, power down, output configuration control, format control, and gain control.

System Interfaces
This chapter describes the TAS5704EVM board in regards to power supply (PSU) and system interfaces.
2.1 PSU Interface
The TAS5704EVM module is powered using two power supply sources a 10–26V (PVCC) power supply
and a 5V (VIN) power supply. The 3.3V voltage levels are generated on the board using voltage regulators
from VIN supply.
Note: The length of power supply cable must be minimized. Increasing length of PSU cable is
equal to increasing the distortion for the amplifier at high output levels and low frequencies.
Maximum output stage supply voltage depends on the speaker load resistance. Check the recommended
maximum supply voltage in the TAS5704 data sheet (SLOS563).

There is no specific power up sequence for TAS5704, but it is recommended to power up the VIN
supply first while reset is kept low for at least 1ms and then power up the PVCC.
2.3 Loudspeaker and Subwoofer Connectors (2-Channel BTL Configuration)
CAUTION
Both positive and negative speaker outputs are floating and may not be
connected to ground (e.g. through an oscilloscope).
•
•
Connect the positive (+) and negative (–) nodes of the left speaker to the corresponding metal binding
post marked OUTA and OUTB on TAS5704EVM board.
Connect the positive (+) and negative (–) nodes of the right speaker to the corresponding metal
binding post marked OUTC and OUTD on TAS5704EVM board.

•
Install jumpers JP3–JP6 and JP7–JP10 for BTL configuration
The subwoofer is an option on this EVM, which is provided through connecting TAS5601EVM2 to the
TAS5704EVM using connector J1. Connector J1 provides the power and corresponding PWMs to the
TAS5601EVM2 (subwoofer amplifier). TAS5601EVM2 is configured in PBTL and is able to provide
40W to an 8-Ω speaker. Connect the subwoofer positive and negative nodes to the corresponding
metal binding posts on the TAS5601EVM2.
2.4 Digital Audio Interface SPDIF (J1/OPTO)
The Digital Audio Interface contains digital audio signal data (I2S). See TAS5704 Data sheet (SLOS563)
for signal timing and details not explained in this document.
RCA connector and OPTO connector are the two SPDIF interfaces. The switch S1 is used to toggle
between OPTO and RCA connector based on available signal source. Once the RCA cable or optical
cable is connected and the signal source is powered up, please verify the SPDIF lock indicator (blue
LED3) to make sure there is viable signal available to the device.
The format of the DIR9001 SPDIF receiver can be changed using jumpers FMT0 and FMT1. Jumpers
installed = 0. Jumpers removed = 1. The description of possible modes is printed on the EVM.
See the schematic of TAS5704EVM and the DIR9001 device for detail information on method by which
the data and clocks are provided to TAS5704.

Jumpers and Control Utilities
2.5 ADC Interface
In the absence of digital signal source ADC (PCM1808) may be used to convert an analog audio signal to
digital signal and provide it to TAS5704. DIR9001 still provides clocks to ADC in this process. The
frequency of the oscillator selected for DIR 9001determinse the sampling frequency in the absence of
digital signal. If the OSC is 24MHz the sampling frequency will be set at 96kHz and if the OSC is selected
to be 12MHz the sampling frequency will be defaulted to 48kHz when there is no signal on SPDIF input
terminals. ADC is an additional feature to this board to provide flexibility in sourcing audio signal to
TAS5704. Please review the datasheet of PCM1808 for detail description of the ADC on this EVM.
2.6 Board Power up General Guidelines
After connecting the loud speakers (loads), power supply, and data line, power up the VIN power supply.
Then power up the PVCC power supply. It is recommended to set the PVCC level to 10 volts and then
ramp it up to 20 volts to verify the cable connection functionality. It is recommended to set the gain to
–3dB at start by having both GAIN (GAIN0 and GAIN1) jumpers inserted. Note that the gain settings
marked on the EVM are not correct. Please see Table 3 on the next page for the correct settings. Having
jumpers FM0 and FM1 inserted and FM2 removed sets the data format for the device to I2S format. Make
sure the SPDIF format jumpers, FMT0 and FMT1 are removed to set the receiver format to I2S. It is
important to note that a device RESET (S2 on the top of the board labeled MASTER RESET) needs to be
applied after each gain, format, or configuration change in order for the device to latch in the new settings.
Finally, install jumpers CFG1 and CFG2 in the Config Control to select 2-CH-BTL-AD mode.

Jumpers and Control Utilities
3.1 Clock Frequency Change Jumper
JP1: In the presence of a valid digital signal input, when SPDIF lock occurs, the user may use JP1 to
change LR clock and BIT clock. When a shunt is inserted, the SCKO = 512Fs and when the shunt is
removed the SCKO = 256Fs. Default is SCKO = 256Fs.
In the absence of a valid digital signal DIR9001 clock outputs switch to the frequency of crystal (Y1). If the
crystal is chosen to be 24MHz the LR clock will be 96KHz and if the crystal is chosen to be 12MHz the LR
clock will be 48kHz.
3.2 SPDIF/PSIA Utilization Jumpers
The jumpers MCLK, LRCK, SCLK, SDATA allow the user to switch between the internal clock and data
sources and external clock and data sources for instance PSIA (from AP instrument). The default
configuration of these jumpers is SPDIF as it is marked on the EVM with a white arrow. PSIA outputs may
be utilized using pins 2 and 3 of the jumpers. Keep in mind that pin 3 of each jumper is connected to
GND. Thus, the user must pay attention to the polarity of the PSIA output cables at the time of insertion.
3.3 Data Routing Jumpers
Jumpers SDIN1, SDIN2: These jumpers enable the user to assign a data source to TAS5704 SDIN1 and

Jumpers and Control Utilities
3.4 GAIN Jumpers
GAIN0 and GAIN1 jumpers enable the user to change the gain of the device. It is important to assert
RESET (S2 labeled MASTER RESET) after each gain change in order for the device to recognize the new
gain configuration. The truth table is shown below and also it is marked on the EVM board. However, the

3.5 Data Format Jumpers
FM0, FM1, and FM2 are used to change the data format by which TAS5704 operates. FMT0 and FMT1
jumpers associated with DIR9001 in SPDIF interface enables the user to change the data format of
DIR9001 so that the data format is in sync with TAS5704 data format. Both TAS5704 and DIR9001 are
set by default to operate at 24-bit I2S format. It is important to assert RESET after each format change in
order for the device to recognize the format change. The truth tables below indicate the jumper
configuration and the data format of TAS5704 and DIR9001 (SPDIF).

DISCLAIMER
The information and materials ("Materials") provided here are provided by Texas Instruments Incorporated ("TI") as
a service to its customers and/or suppliers, and may be used for informational purposes only, and only subject to
the following terms. By downloading or viewing these Materials, you are signifying your assent to these terms.
1.) These preliminary evaluation schematics are intended for use for PRELIMINARY ENGINEERING DEVELOPMENT
AND EVALUATION PURPOSES ONLY and are not considered by Texas Instruments to be fit as a basis for
establishing production products or systems. This information may be incomplete in several respects, including but
not limited to information relating to required design, marketing, and/or manufacturing-related protective considerations
and product safety measures typically found in the end-product incorporating the goods.
2.) Accordingly, neither TI nor its suppliers warrant the accuracy or completeness of the information, text, graphics,
links or other items contained within the Materials. TI may make changes to the Materials, or to the products described
therein, at any time without notice. TI makes no commitment to update the Materials.
3.) TI assumes no liability for applications assistance, customer product design, software performance, or services that
may be described or referenced in the Materials. The user assumes all responsibility and liability for proper and safe
design and handling of goods. Accordingly, the user indemnifies TI from all claims arising from its use of the Materials.
4.) TI currently deals with various customers for products, and therefore our arrangement with the user will not be
exclusive. TI makes no representations regarding the commercial availability of non-TI components that may be
referenced in the Materials.
5.) No license is granted under any patent right or other intellectual property right of TI covering or relating to any
combination, machine, or process in which such TI products or services might be or are used. Except as expressly
provided herein, TI and its suppliers do not grant any express or implied right to you under any patents, copyrights,
trademarks, or trade secret information.
6.) Performance tests and ratings, to the extent referenced in the Materials, are measured using specific computer
systems and/or components and reflect the approximate performance of TI products as measured by those tests. Any
difference in system hardware or software design or configuration may affect actual performance. Buyers should consult
other sources of information to evaluate the performance of systems or components they are considering purchasing.
7.) Resale of TI's products or services with statements different from or beyond the parameters stated by TI for that
product or service in official TI data books or data sheets voids all express and any implied warranties for the associated
TI product or service, and is an unfair and deceptive business practice, and TI is not responsible for any such use.
8.) The Materials are copyrighted and any unauthorized use may violate copyright, trademark, and other laws. You may
only download one copy for your internal use only, unless you are specifically licensed to do otherwise by TI in writing.
This is a license, not a transfer of title, and is subject to the following restrictions: You may not:
(a) modify the Materials (including any associated warranties, conditions, limitations or
notices) or use them for any commercial purpose, or any public display, performance, sale or
rental;
(b) decompile, reverse engineer, or disassemble software Materials except and only to the
extent permitted by applicable law;
(c) remove any copyright or other proprietary notices from the Materials;
(d) transfer the Materials to another person. You agree to prevent any unauthorized copying
of the Materials. TI may terminate this license at any time if you are in breach of the terms
of this Agreement. Upon termination, you will immediately
destroy the Materials.
9.) THE MATERIALS ARE PROVIDED "AS IS" WITHOUT ANY EXPRESS OR IMPLIED WARRANTY OF ANY KIND
INCLUDING WARRANTIES OF MERCHANTABILITY, NONINFRINGEMENT OF INTELLECTUAL PROPERTY, OR
FITNESS FOR ANY PARTICULAR PURPOSE. IN NO EVENT SHALL TI OR ITS SUPPLIERS BE LIABLE FOR ANY
DAMAGES WHATSOEVER (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, BUSINESS

FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio
frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are
designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may
be required to correct this interference.
EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range (PVCC and VIN, correspondingly) of 26 V at 3 A, 5 V at 500 mA and
output power of 20 W maximum.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions
concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.
Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 60°C. The EVM is designed to operate
properly with certain components above 60°C as long as the input and output ranges are maintained. These components include but are
not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified
using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,
please be aware that these devices may be very warm to the touch.
