Description
The WM8903 is a high performance ultra-low power stereo CODEC optimised for portable audio applications.
Features
- stereo ground-referenced headphone amplifiers using the Wolfson ‘Class W’ amplifier techniques incorporating an innovative dual-mode charge pump architecture - to optimise efficiency and power consumption during playback. The ground-referenced outputs eliminate headphone coupling capacitors. Both headphone and line 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 sequencer to reduce software.
