AGC IC for telephone speech network

■ Overview

Unit: mm

The AN6215S is an AGC IC for telephone speech

network, and it incorporates an microphone input detec-

tion circuit and a receiver gain control circuit. It is espe-

cially best suited for cordless telephone thanks to a good

speech tone quality obtained by reducing howling and echo

sound.

■ Features

• Operation with wide power supply voltage range from

2.1 V to 6.0 V

0.3

• Enlargement of dynamic range by incorporating a vari-

able V_REFcircuit that varies according to the supply

voltage

4.2 ± 0.3

6.5 ± 0.3

• Possible to adjust the received voice attenuation amount

with an external resistor

SOP008-P-0225A

• Possible to adjust the AGC operating point with an ex-

ternal resistor

• Possible to design with fewer external components
