AN6215S
AGC IC for telephone speech network
1
I
Overview
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.
I
Features
Operation with wide power supply voltage range from
2.1 V to 6.0 V
Enlargement of dynamic range by incorporating a
vari-
able V
REF
circuit that varies according to the supply
voltage
Possible to adjust the received voice attenuation amount
with an external resistor
Possible to adjust the AGC operating point with an ex-
ternal resistor
Possible to design with fewer external components
