ML2612 FAMILY DATASHEET
General Description
The ML2612 family is a low power small size monaural CODEC with in-built speaker amplifier, ideally suited for
portable playback and recording applications. The microphone interface (1bit digital) supports MEMS (silicon) digital
microphones for low noise recording systems. For digital signal processing, the ML2612 uses high-pass filters and a
5-band programmable equalizer including 5 channel notch filter to enable flexible sound processing.
