MSM7704-01 2ch Single Rail CODEC FEDL7704-01-01 Issue Date: Jun. 25, 2012 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. FEATURES • Single power supply: +2.7 V to +3.8 V • Power consumption Operating mode: 30 mW Typ. 50 mW Max. Power-saving mode: 3 mW Typ. 6 mW Max. Power-down mode: 0.03 mW Typ.
