MSM7540L/7560L

Single Rail ADPCM CODEC

GENERAL DESCRIPTION

TheMSM7540L/7560LaresinglechannelADPCMCODECICswhichperformmutualtranscoding

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

Using advanced circuit technology, these devices operate from a single 3 V power supply and

provide low power consumption.
