2ch Single Rail CODEC
GENERAL DESCRIPTION
The MSM7704-01/7704-02/7704-03 are two-channel CODEC CMOS ICs for voice signals ranging
from 300 to 3400 Hz. These devices contain filters for A/D and D/A conversion.
Designed especially for a single-power supply and low-power applications, these devices
contain two-channel AD/DA converters in a single chip and achieve a reduced footprint and a
reduced number of external components.
The MSM7704-01/7704-02/7704-03 are best suited for an analog interface to an echo canceller
DSP used in digital telephone terminals, digital PABXs, and hands free terminals.
