WM8524
24-bit 192kHz Stereo DAC with 2Vrms
Ground Referenced Line Output
DESCRIPTION
The WM8524 is a stereo DAC with integral charge pump
and hardware control interface. 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 WM8524 has a 3.3V tolerant digital interface, allowing
logic up to 3.3V to be connected.
The device is available in a 16-pin TSSOP.
