WM8523 Datasheet | Wolfson Microelectronics

w 24-bit 192k Hz Stereo DAC with 2Vrms Ground Referenced Line Output 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 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 rates. Master and Slave modes are available and deemphasis 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.
