MSM7533V Datasheet PDF - LAPIS Semiconductor Co., Ltd.

GENERAL DESCRIPTION
   The MSM7533V 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 MSM7533V is best suited for an analog interface to an echo canceller DSP used in digital telephone terminals, digital PABXs, and hands free terminals.
