Cirrus Logic, Inc. 106 dB, Variable Sample Rate D/A converter with Charge Pump, Line Driver and Software Control WM8533

The WM8533 is a stereo digital/analog (DAC) with integral charge pump and software control interface to provide 2 VRMS line driver outputs using a 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 WM8533 is controlled and configured either via I²C/SPI compliant serial control interface or a hardware control interface, and supports audio sampling rates between 8 kHz and 192 kHz using all common MCLK/fs ratios. Master and slave modes are available and de-emphasis is also supported. Features Digital volume control from -100 dB to +12 dB I²C/SPI compatible and hardware control modes Data formats: LJ, RJ, I²S, DSP De-emphasis supported Maximum 1 mV DC offset on line outputs
