Features

AI Translation
  • The WM8904 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 headphone and line outputs eliminate AC coupling capacitors, and both 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 minimise pops and clicks via SilentSwitch™ technology.
  • The analogue input stage can be configured for single ended or differential inputs.
  • Up to 3 stereo microphone or line inputs may be connected.
  • The input impedance is constant with PGA gain setting.
  • A stereo digital microphone interface is provided, with a choice of two inputs.
  • A dynamic range controller provides compression and level control to support a wide range of portable recording applications.
  • Anti-clip and quick release features offer good performance in the presence of loud impulsive noises.
  • ReTuneTM Mobile 5-band parametric equaliser with fully programmable coefficients is integrated for optimization of speaker characteristics.
  • Programmable dynamic range control is also available for maximizing loudness, protecting speakers from clipping and preventing premature shutdown due to battery droop.
  • Common audio sampling frequencies are supported from a wide range of external clocks, either directly or generated via the FLL.
  • The WM8904 can operate directly from a single 1.8V switched supply.
  • For optimal power consumption, the digital core can be operated from a 1.0V supply.
  • 3.0mW quiescent power consumption for DAC to headphone playback
  • DAC SNR 96dB typical, THD -86dB typical
  • ADC SNR 91dB typical, THD -80dB typical
  • 2.4mW quiescent power consumption for analogue bypass playback
  • Control write 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
