24-bit 192kHz Stereo D/A Converter with 2VRMS Ground Referenced Line Output

The WM8524 is a stereo digital/analog converter (DAC) with integral charge pump and hardware control interface that provides 2 VRMS line driver outputs using a single 3.3 V power supply rail. The device features ground-referenced outputs and the use of a DC servo to eliminate the use of line driving coupling capacitors as well as power on pops and clicks. The WM8524 is controlled and configured via a hardware control interface and supports audio sampling rates between 8 kHz and 192 kHz using all common MCLK/fs ratios. The audio interface operates in secondary mode.



  • Hardware control mode
  • Data formats: LJ, RJ, I²S
  • Maximum 1 mV DC offset on line outputs
  • Pop/click suppressed
