MSM7540/7560

Single Rail ADPCM CODEC

GENERAL DESCRIPTION

TheMSM7540/7560aresinglechannelADPCMCODECICswhichperformmutualtranscoding

between an analog voice band signal 300 to 3400 Hz and 32 kbps ADPCM serial data.

Using advanced circuit technology, these devices operate using a single 5 V power supply and

have low power consumption.

The MSM7540/7560 are optimized for advanced digital cordless telephone system applications.
