WM1824
24-bit 192kHz Stereo DAC with 2Vrms Ground Referenced Line Output
DESCRIPTION
The WM1824 is a stereo DAC with integral charge pump. This provides 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 WM1824 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected.
The device is available in a 24-pin QFN.
FEATURES
High performance stereo DAC with ground referenced line driver
