WM8903規(guī)格書詳情
DESCRIPTION
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)
