Panasonic AN6167SB, AN6167S Datasheet
■ Overview
The AN6167S and AN6167SB are speech network ICs for
the handset of a cordless telephone. They incorporate compander, 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-transmission noise.
■ Features
•
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.
