WM8523

w WM8523 24-bit 192kHz 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 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 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.
