DAC 2-CH Resistor-String 24-bit 24-Pin QFN

The WM8532 is a stereo DAC with integral charge pump. This provides selectable 1VRMS or 2VRMS line driver outputs using a single 3.3V power supply rail.The device features ground-referenced outputs and the use of a DC servo to eliminate the need for line driving coupling capacitors and effectively eliminate power on pops and clicks.The device is controlled and configured via a hardware control interface.The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. The audio interface operates in slave mode.The WM8532 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected.The device is available in a 24pin QFN.
