The WM8523 is a stereo digital/analog converter (DAC) with integral charge pump and software control interface to provide 2Vrms line driver outputs using a single 3.3V power supply rail. This IC 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 device is controlled and configured either via the 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.
