MSM7534 Datasheet (MSM7533) 2ch Single Rail CODEC

Manufacturer: OKI Electric

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.
