GENERAL DESCRIPTION
The MSM7704-01 is 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 is best suited for an analog interface to an echo canceller DSP used in digital telephone terminals, digital PABXs, and hands free terminals.
