Single Rail CODEC
GENERAL DESCRIPTION
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.
The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B.
The analog output signal can directly drive a piezoelectric type handset receiver.
