Chapter 1

Introduction

The true digital audio amplifiers (TDAA) system consists of a PCM–PWM

modulator device and a PWM power output device. The PCM–PWM

processor accepts a serial PCM digital audio stream and converts it to a 3.3-V

PWM audio stream. The TDAA output stage provides a large-signal PWM

output. The digital PWM signal is then demodulated providing power output

for driving loudspeakers. This patented technology provides low cost, high

quality, high efficient digital audio applicable to many audio systems

developed for the digital age.

The TAS5110D6REF reference design demonstrates the integrated circuit

TAS5110DAD from Texas Instruments (TI). The board does not contain any

PWM processors. A separate and compatible PWM processor board (such as

TAS5026REF) is available.

The TAS5110 is a single channel PWM power audio device. It contains

integrated gate drivers, four matched and electrically isolated

enhancement-mode N-channel power DMOS transistors, and protection and

fault-reporting circuitry. This device is optimized for use with the TAS50XX

PWM processor family.

Together with the TAS5026REF module or the TAS5036REF module, the

TAS5110D6REF module is a complete true digital audio amplifier system,

which includes digital volume control, headphone amplifier, and a subwoofer

output.

1.3 Short-Circuit Protection and Fault Reporting Circuitry

The TAS5110 is a self-protecting device that provides device fault reporting

(including over-temperature protect and short-circuit protection).

1.3.1 Device Fault Reporting

The ERR0, ERR1, and SHUTDOWN outputs from TAS5110 indicates the

device conditions shown in Table 1–1. The device fault reporting outputs are

open-drain outputs.

Normal operation

1.3.2 Short-Circuit Protection

The short-circuit protect error condition latches the TAS5110 in the shutdown

mode:

- H-bridge outputs (OUTPUTA and OUTPUTB) are in a high-impedance

state (Hi-Z state).

- SHUTDOWN is asserted low.

- ERR0 is high and ERR1 is asserted low.

- The H-bridge outputs remains in a Hi-Z state until the device is reset

(RESET pin asserted low).

The TAS5110 is not designed for driving load impedance less than 4 Ω (at

20-Vdc output stage supply), where the internal current limit protection is

activated at high power levels.

1.3.3 Auto Recovery System

Together with a PWM processor from Texas Instruments (e.g., the TAS5026

or the TAS5036), the TAS5110 can be configured in autorecovery mode. The

SHUTDOWN signal from the TAS5110 is in autorecovery mode connected to

ERR_RCVY at the PWM processor.

The short-circuit protect error condition results in the following autorecovery

sequence:

PCB Key Map

- H-bridge outputs (OUTPUTA and OUTPUTB) are in a high-impedance

state (Hi-Z state).

- ERR_RCVY at the PWM processor is forced low by the SHUTDOWN

signal.

- RESET at the TAS5110 is forced low by the VALID signal.

- The VALID signal goes high after 4 ms and then the TAS5110 starts

switching again.

PSU Interface (J150)

2.1 PSU Interface (J150)

The TAS5110D6DAD board must be powered from external power supplies.

High-end audio performance requires a stabilized power supply with low ripple

voltage and low output impedance.

Note:

The length of the power-supply cable must be minimized. Increasing the

impedance of the PSU cable is equal to increasing the distortion for the

amplifier at high output levels and low frequencies.

The maximum output stage supply voltage depends on the speaker load

resistance. See the recommended maximum supply voltage in Chapter 4.

The recommended TAS5110 power-up sequence is shown in Figure 2–1. For

proper TAS5110operation, theRESET signal should be kept low during power

up. RESET is pulled low during power up for 100 ms by the onboard low-drop

linear regulator (U170).
