简  介:WM8774 24-bit, 192kHz 8-Channel Input Stereo Codec DESCRIPTION The WM8774 is a high performance, stereo audio codec with an 8 channel input selector. The WM8774 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. A stereo 24-bit multi-bit sigma delta DAC is 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 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-pin TQFP package. FEATURES Audio Performance 106dB SNR (‘A’ weighted @ 48kHz) DAC 101dB SNR (‘A’ weighted @ 48kHz) ADC DAC Sampling Frequency: 8kHz – 192kHz ADC Sampling Frequency: 8kHz – 96kHz 3-Wire SPI Compatible Serial Control Interface M……
