FUNCTION DESCRIPTION
1. This IC built•in ALC detect circuit. When input large signal, the ALC become high level, and control the output
amplitude; when input small signal, the ALC is shut down, output gain is fixed.
2. Voltage gain of amplifier is determined by the built•in negative feedback resistance.
