MSM7728 Overview
The MSM7728 is a single-channel linear CODEC CMOS IC for voice signals that contains filters for A/D and D/A conversions. Designed especially for a single-power supply and low-power applications, the device is optimized for applications for the analog interfaces of audio signal processing DSPs and digital wireless systems. The analog outputs include the speaker drive output, earphone drive output and ringer output.
