6-channel DAC with volume control
FEATURES 6-Channel DAC with 1.7Vrms line driver from 5V analogue supply Audio performance - SNR 102dB (‘A’ weighted @ 48kHz) - THD -85dB (48kHz) DAC sampling frequency: 8kHz – 192kHz 3-Wire SPI serial or hardware control interface Programmable audio data interface modes - I²S, left, right justified or DSP - 16/20/24/32 bit word lengths Three independent stereo DAC outputs with independent digital volume controls Master or slave audio data interface 4.5V to 5.5V analogue, 2.7V to 3.6V digital supply operation Pin compatible with WM8766 28-lead SSOP package	DESCRIPTION The WM8522 is a multi-channel audio DAC ideal for DVD and surround sound processing applications for home hi-fi, automotive and other audio visual equipment. Three stereo 24-bit multi-bit sigma delta DACs are used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 192kHz are supported. Each DAC channel has independent digital volume and mute control, and provides 1.7Vrms line drive capability from a 5V supply. This makes the device ideal for cost-sensitive consumer applications requiring high line drive audio outputs. The audio data interface supports I²S, left justified, right justified and DSP digital audio formats. The device is controlled via a 3 wire serial interface or directly using the hardware interface. These interfaces provide access to features including channel selection, volume controls, mutes, de-emphasis and power management facilities. The device is available in a 28-lead SSOP.
