The WM8912 is an ultra low power stereo digital/analog converter (DAC) with integrated ground-referenced headphone amplifiers that incorporate a dual-mode charge pump to optimize efficiency and power consumption during playback. The ground-referenced outputs eliminate headphone coupling capacitors and the outputs include common mode feedback paths to reject ground noise. Control sequences for audio path setup can be pre-loaded and executed by an integrated control write sequencer to reduce software driver development and minimize pops and clicks. The WM8912 can operate directly from a single 1.8V switched supply, or for optimal power consumption, the digital core can be operated from a 1V supply.
