Details
The WM8903 is a high performance ultra-low power stereo CODEC optimised for portable audio applications. The device 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.FEATURES 4.5mW power consumption for DAC to headphone playback DAC SNR 96dB typical, THD -86dB typical ADC SNR 92dB typical, THD -80dB typical Control sequencer for pop minimised start-up and shutdown Single register write for default start-up sequence Integrated FLL provides all necessary clocks - Self-clocking modes allow processor to sleep - All standard sample rates from 8kHz to 96kHz Stereo digital microphone input 3 single ended inputs per stereo channel 1 fully differential mic / line input per stereo channel Digital Dynamic Range Controller (compressor / limiter) Digital sidetone mixing Ground-referenced headphone driver Ground-referenced line outputs Stereo differential line driver for direct interface to WM9001speaker driver 40-pin QFN package (5x5mm)
