WM8533 Datasheet | Wolfson Microelectronics

DESCRIPTION The WM8533 is a stereo DAC with integral charge pump and software control interface. This provides 2Vrms line driver outputs using a 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 pliant serial control interface or a hardware control interface. The device supports all mon audio sampling rates between 8k Hz and 192k Hz using all mon MCLK / fs ratios. Master and slave modes are available and deemphasis is also supported. The WM8533 has a 1.8 to 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected. The device is available in a 1.842 x 1.772mm 20-ball WCSP.
