2ch Single Rail CODEC
GENERAL DESCRIPTION
The MSM7533 and MSM7534 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 MSM7533 and MSM7534 are best suited for an analog interface to an echo canceller DSP used
in digital telephone terminals, digital PABXs, and hands free terminals.
