Cirrus Logic, Inc. 100 dB, Variable Sample Rate D/A Converter with Charge Pump, Line Driver and Software Control WM8523

The WM8523 is a stereo digital/analog converter (DAC) with integral charge pump and software control interface to provide 2 VRMS line driver outputs using a single 3.3 V 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 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
