Single Rail Linear CODEC
This version: A_Mug_S._M19₇9₇8₁₆
Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM7716 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.
