FUNCTIONAL DESCRIPTION
The TDA8563Q contains 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 (
<
100
μ
A)
Mute: input signal suppressed
Operating: normal on condition.
Since this pin has a very low input current (
<
40
μ
A), a low
cost supply switch can be applied.
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 pin 1 and pin 13).
This can be achieved by:
Microprocessor control
External timing circuit (see Fig.7).
Diagnostic output (pin 12)
D
YNAMIC 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).
