MSM7579 Overview
The MSM7578 and MSM7579 are single-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 are particularly optimized for telephone terminals in digital wireless systems and ISDN systems.
