描述:
DESCRIPTION The WM8776 is a high performance, stereo audio CODEC with five channel input selector. The WM8776 is ideal for surround sound processing applications for home hi-fi, DVD-RW and other audio visual equipment. A stereo 24-bit multi-bit sigma delta ADC is used with a five stereo channel input mixer. Each ADC channel has programmable gain control with automatic level control. Digital audio output word lengths from 16-32 bits and sampling rates from 32kHz to 96kHz are supported. A stereo 24-bit multi-bit sigma delta DAC is used with digital audio input word lengths from 16-32 bits and sampling rates from 32kHz to 192kHz. The DAC has an input mixer allowing an external analogue signal to be mixed with the DAC signal. There are also Headphone and line outputs, with volume controls for the headphones. FEATURES • Audio Performance    − 108dB SNR (‘A’ weighted @ 48kHz) DAC    − 102dB SNR (‘A’ weighted @ 48kHz) ADC • DAC Sampling Frequency: 32kHz – 192kHz • ADC Sampling Frequency: 32kHz – 96kHz • Five stereo ADC inputs with analogue gain adjust from +24dB to –21dB in 0.5dB steps • Programmable Limiter or Automatic Level Control (ALC) • Stereo DAC with independent analogue and digital volume controls • Stereo Headphone and Line Output • 3-Wire SPI Compatible or 2-Wire Software Serial Control Interface • Master or Slave Clocking Mode • Programmable Audio Data Interface Modes    − I2S, Left, Right Justified or DSP    − 16/20/24/32 bit Word Lengths • Analogue Bypass Path Feature • Selectable AUX input to the volume controls • 2.7V to 5.5V Analogue, 2.7V to 3.6V Digital supply Operation APPLICATIONS • Surround Sound AV Processors and Hi-Fi systems • DVD-RW
