AN6167S, AN6167SB
Cordless Telephone Speech Network IC
the handset of a cordless telephone. They incorporate compan-
der, MIC, and receiver amplifiers. With a minimal number of
external components, they can perform all the functions of the
handset of a cordless telephone featuring low radio-transmis-
sion noise.
•

•
The compressor/expander circuit incorporates preamplifiers
to make level and frequency adjustments easier.
The standby circuit provides for a low-power consumption
cordless telephone.
The expander has a 6-dB amplifier to allow received-signal
amplificaition.
SOP package with 1.27mm pitch pins, and USO package
with 0.8mm pitch pins.
The AN6167S and AN6167SB are speech network ICs for
