FUNCTIONAL DESCRIPTION  
The TDA8560Q contains two identical amplifiers and can  
be used for bridge applications. The gain of each amplifier  
is fixed at 40 dB. Special features of the device are as  
follows.

To avoid switch-on plops, it is advised to keep the amplifier

At the onset of clipping of one or more output stages, the  
dynamic distortion detector becomes active and pin 12  
goes low. This information can be used to drive a sound  
processor or DC volume control to attenuate the input  
signal and thus limit the distortion. The output level of  
pin 12 is independent of the number of channels that are  
clipping (see Fig.3).

During this short-circuit condition, pin 12 is low for 20 ms  
SHORT-CIRCUIT PROTECTION  
and high for 50 µs (see Fig.4).  
When a short-circuit occurs at one or more outputs to  
ground or to the supply voltage, the output stages are  
switched off until the short-circuit is removed and the  
device is switched on again, with a delay of approximately  
20 ms, after removal of the short-circuit. During this  
short-circuit condition, pin 12 is continuously low.  
The power dissipation in any short-circuit condition is  
very low.  
TEMPERATURE DETECTION  
When the virtual junction temperature Tvj reaches 150 °C,  
pin 12 will become continuously low.  
When a short-circuit across the load of one or both  
channels occurs the output stages are switched off during  
approximately 20 ms. After that time it is checked during  
approximately 50 µs to see whether the short-circuit is still  
present. Due to this duty cycle of 50 µs/20 ms the average  
current consumption during this short-circuit condition is  
very low (approximately 40 mA).  
OPEN COLLECTOR OUTPUT  
Pin 12 is an open collector output, which allows pin 12 of  
more devices being tied together.

The device may be mounted up to the seating plane, but  
the temperature of the plastic body must not exceed the  
specified maximum storage temperature (Tstg max). If the  
printed-circuit board has been pre-heated, forced cooling  
may be necessary immediately after soldering to keep the  
temperature within the permissible limit.  
SOLDERING  
Introduction  
There is no soldering method that is ideal for all IC  
packages. Wave soldering is often preferred when  
through-hole and surface mounted components are mixed  
on one printed-circuit board. However, wave soldering is  
not always suitable for surface mounted ICs, or for  
printed-circuits with high population densities. In these  
situations reflow soldering is often used.  
Repairing soldered joints  
Apply a low voltage soldering iron (less than 24 V) to the  
lead(s) of the package, below the seating plane or not  
more than 2 mm above it. If the temperature of the  
soldering iron bit is less than 300 °C it may remain in  
contact for up to 10 seconds. If the bit temperature is  
between 300 and 400 °C, contact may be up to 5 seconds.  
This text gives a very brief insight to a complex technology.  
A more in-depth account of soldering ICs can be found in  
our “IC Package Databook” (order code 9398 652 90011).  
Soldering by dipping or by wave  
The maximum permissible temperature of the solder is  
260 °C; solder at this temperature must not be in contact  
with the joint for more than 5 seconds. The total contact  
time of successive solder waves must not exceed  
5 seconds.
