AF BYPASS
AF bypass terminal. It is
connected to one of the input of
a differential amplifier, external
capacitor provides AC filtering.
When resistor is connected in
series with capacitor, it is
possible to lows the amplitude of
the audio output. When audio
output terminal is not used,
please connect pin 22 to GND.
