Description

The MSM7702-02 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 MSM7702-02 utilizes low-voltage operational amplifiers (Op-amps) to provide low-power consumption.

The MSM7702-02 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.
