DESCRIPTION

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 or 24-lead

QFN.
