Product specication
4 x 12 W single-ended car radio power amplier with
dynamic distortion detector and diagnostic interface
TDA8562Q
Mode select switch
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 pins 1, 3, 15 and 17.
The circuit in Fig.7 slowly ramps up the voltage at the
mode select switch pin when switching on and results in
fast muting when switching off.
