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.

in digital telephone terminals, digital PABXs, and hands free terminals.
