ML7041
Audio CODEC
GENERAL DESCRIPTION
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 control, side-tone path, and
low-dropout regulator, the ML7041 is best suited for telephone terminals in digital wireless systems.
