TheTDA8563AQcontains two identical amplifiers and can
be used for bridge applications. The gain of each amplifier
is fixed at 26 dB. Special features of the device are as
follows.
Mode select switch (pin 11)
• Standby: low supply current
• Mute: input signal suppressed
• Operating: normal on condition.
Since this pin has a very low input current (<40 µA), a low
cost supply switch can be applied.
Toavoidswitch-on plops, it is advised to keeptheamplifier
in the mute mode during ≥100 ms (charging of the input
capacitors at pin 1 and pin 13). During switching from
standby to mute, the slope should be at least 18 V/s.
This can be achieved by:
• Microprocessor control
• External timing circuit (see Fig.7).

Diagnostic output (pin 12)
DYNAMIC DISTORTION DETECTOR (DDD)
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).

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
20 ms, after removal of the short-circuit. During this
short-circuit condition, pin 12 is 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).

During this short-circuit condition, pin 12 is LOW for20 ms
and HIGH for 50 µs (see Fig.4).
The power dissipation in any short-circuit condition is very
low.
TEMPERATURE DETECTION
When the virtual junction temperature Tvjreaches 150 °C,
pin 12 will become continuously low.
OPEN COLLECTOR OUTPUT
Pin 12 is an open collector output, which allows pin 12 of
more devices being tied together.
