The ultra low power WM8963 stereo codec features a programmable audio enhanced DSP, 2 watt per channel speaker drivers and Class W headphone drivers. An integrated charge pump provides a ground referenced output that eliminates the need for DC-blocking capacitors on the headphone outputs and incorporates a dual-mode charge pump architecture to optimize efficiency and power consumption during playback.
