6-Channel D/A Converter with Volume Control

The WM8766 is a multichannel audio digital/analog converter (DAC) featuring three stereo 24-bit multi-bit Delta Sigma DACs with oversampling digital interpolation filters. This device accepts data input from 16 to 32-bits and works with sampling rates from 8 kHz to 192 kHz. Each DAC channel has independent digital volume and mute control. The audio data interface supports I2S, left justified, right justified and DSP digital audio formats. The device is controlled either 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.
