HANGZHOU SILAN MICROELECTRONICS CO.,LTD REV:1.3 2006.05.22 Http: www.silan.com.cn Page 3 of 4 FUNCTION DESCRIPTION 1. This IC builtin 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 builtin negative feedback resistance.
