MSM7702 Overview
The MSM7702 is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz with filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, the device is optimized for telephone terminals in digital wireless systems or ISDN systems. The MSM7702 utilizes low-voltage operational amplifiers (Op-amps) to provide low-power consumption.
