AN3969K

Electronic volume IC for HiFi VCR

■ Overview

The AN3969K is a stereo electronic volume IC
which has been developed for a HiFi video, en­abling 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
