FUNCTIONAL DESCRIPTIONThe TDA8561Q contains four identical amplifiers and can
be used for Single-Ended (SE) or Bridge-Tied Load (BTL)
applications. The gain of each amplifier is fixed at 20dB
(26 dB in BTL). Special features of the device are:
Mode select switch (pin 14) Low standby current (<100 μA) Low switching current (low cost supply switch) Mute facility.
To avoid switch-on plops, it is advised to keep the amplifier
in the mute mode during ≥100 ms (charging of the input
capacitors at pins1,3,15 and 17). This can be achieved
by: Microcontroller control External timing circuit (see Fig.11).
Diagnostic output (pin 16)DYNAMIC DISTORTION DETECTOR (DDD)
At the onset of clipping of one or more output stages, the
dynamic distortion detector becomes active and pin16
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 16 is independent of the number of channels that are
clipping (see Figs3 and4).
SHORT-CIRCUIT PROTECTION
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 ms, after removal of the short-circuit. During this
short-circuit condition, pin 16 is continuously LOW.
When a short-circuit across the load of one or both
channels occurs the output stages are switched off for
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).
During this short-circuit condition, pin 16 is LOW for 20 ms
and HIGH for 50 μs (see Fig.5).
The power dissipation in any short-circuit condition is very
low.

TEMPERATURE DETECTION
When the virtual junction temperature Tvj reaches 150 °C, pin 16 will be active LOW.
OPEN-COLLECTOR OUTPUT
Pin 16 is an open-collector output, which allows pin 16 of more devices being tied together.
