AN3969K

Electronic volume IC for HiFi VCR

■Overview

The AN3969K is a stereo electronic volume IC

which has been developed for a HiFi video, en-

abling to switch four inputs of a single channel and

to input from microphone.

■Features

•Both L/R-independent volume control and balance

control are available

•Switching four inputs with a single channel is

possible

•Electronic volume off function

•Mic. mixing function

■Applications

•HiFi VCR SDIP022-P-0300A
