ML7041 Overview
The ML7041 is a single-channel full duplex CODEC LSI device which performs mutual transcoding between the analog voice band signals ranging from 300 to 3400 Hz and the 64 kbps PCM serial data. Provided with such functions as DTMF Tone generation, transmit/receive data gain c ontrol, side-tone path, and low-dropout regulator, the ML7041 is best suited for telephone terminals in digital wireless systems.
