DAC Sampling Frequency: 32kHz – 192kHz
ADC Sampling Frequency: 32kHz – 96kHz
The stereo 24-bit multi-bit sigma delta ADC has programmable
gain with limiting control. Digital audio output word lengths from
16-32 bits and sampling rates from 32kHz to 96kHz are
supported.
Stereo ADC input analogue gain adjust from +24dB to –21dB in
0.5dB steps

ADC digital gain from -21.5dB to -103dB in 0.5dB steps
Programmable Limiter on ADC input.
A stereo multi-bit sigma delta DAC is used with digital audio
input word lengths from 16-32 bits and sampling rates from
32kHz to 192kHz.
Stereo DAC with differential analogue line outputs.
3-Wire SPI Compatible Control Interface
Master or Slave Clocking Mode
The WM8590 supports fully independent sample rates for the
ADC and DAC. The audio data interface supports I2S, left
justified, right justified and DSP formats.
