GENERAL DESCRIPTION
The MSM7716P is an extended temperature range version for the MSM7716 which is a single-channel CODEC
CMOS IC for voice signals that contains filters for linear A/D and D/A conversion.
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 output signal can directly drive a ceramic type handset receiver. In addition, levels for analog outputs
can be set by external control.
