DESCRIPTION
The WM8770 is a high performance, multi-channel audio codec. The WM8770 is ideal for surround sound processing applications for home hi-fi, automotive and other audio visual equipment. A stereo 24-bit multi-bit sigma delta ADC is used with an eight stereo channel input selector. Each channel has analogue domain mute and programmable gain control. Digital audio output word lengths from 16-32 bits and sampling rates from 8kHz to 96kHz are supported. Four 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 analogue volume and mute control, with a set of input multiplexors allowing selection of an external 3 channel stereo analogue input into these volume controls. 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. The interface provides access to all features including channel selection, volume controls, mutes, de-emphasis and power management facilities. The device is available in a 64-lead TQFP package.
