AN6123MS

Speech network IC with ALC

■ Overview

The AN6123MS is an ALC IC for level control of

audio signal (300 Hz to 3 kHz).

Adopting a mini 5-pin package, mounting on a small

area is possible.

■ Features

• Wide supply voltage operation range of VCC = 2.4 V to

6.0 V

• Small current consumption of I

= 500 µA

CC

• Reduction of a bad effect by the external noise thanks to

a package for a rear side mounting.

■ Applications

• Cordless telephone, PDC, PHS telephone
