ML7029 pdf datasheet (Multi-Fu

The ML7029 is a single channel ADPCM Codec LSI device which performs mutual transcoding between the analog voice band signal and 32 kbps ADPCM serial data. The device includes transmit/receive data mute and gain control, and side-tone path and gain control. A wide clock frequency range allows for enhanced voice quality tuning. By using the serial interface, the device allows control of gain, mute, side tone, attenuaTIon, and power-down modes.

Using advanced CMOS circuit technology, this device operates from a single 3-V power supply and provides low power consumpTIon.
