The WM8523 is a stereo DAC with integral charge pump and software 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 either via the I²C/SPI compliant serial control interface or a hardware control interface.
The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. Master and Slave modes are available and de-emphasis is also supported.
The WM8523 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected.
The device is available in a 20-lead TSSOP package.
