24-bit 192 kHz Stereo D/A Converter with 2VRMS Ground Referenced Line Output

The WM1824 is a stereo digital/analog converter (DAC) with integral charge pump and 2 VRMS line driver that provides outputs using a single 3.3 V power supply rail. The WM1824 has a 3.3V tolerant digital interface to allow logic up to 3.3 V and supports audio sampling rates between 8 kHz and 192 kHz using all common MCLK/fs ratios. The audio interface operates in slave mode and features ground-referenced outputs and the use of a DC servo to eliminate line driving coupling capacitors to effectively eliminate power on pops and clicks.
