The WM8533 is a stereo digital/analog (DAC) with integral charge pump and software control interface to provide 2Vrms line driver outputs using a 3.3V 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 and 192kHz using all common MCLK/fs ratios. Master and slave modes are available and de-emphasis is also supported.
