ADAU1772:  4 ADC, 2 DAC Low-Power Codec with Audio Processor

Product Details

Product Status:Recommended for New Designs

The ADAU1772 is a codec with four inputs and two outputs that incorporates a digital processing engine to perform filtering, level control, signal level monitoring, and mixing. The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise cancelling headsets. With the addition of just a few passive components, a crystal, and an EEPROM for booting, the ADAU1772 provides a complete headset solution.

APPLICATIONS

  • Noise cancelling headsets, headsets, and headphones
  • BlueTooth ANC headsets, headsets, and headphones
  • Personal navigation devices
  • Digital still and video cameras

FEATURES and BENEFITS

  • Programmable audio processing engine
    -- 192 kHz processing path
    -- Biquad filters, limiters, volume controls, mixing
  • Low latency, 24-bit ADCs and DACs
    -- 102 dB SNR (signal through PGA and ADC with A-weighted filter)
    -- 107 dB combined SNR (signal through DAC and headphone with A-weighted filter)
  • Serial port sample rates from 8 kHz to 192 kHz
  • 38 μs analog-to-analog latency
  • Four single-ended analog inputs—configurable as microphone or line inputs
  • Stereo analog audio output—single-ended or differential, configurable as either line output or headphone driver
  • PLL supporting any input clock rate from 8 MHz to
    27 MHz
  • Full-duplex, asynchronous sample rate converters (ASRCs)
  • See data sheet for additional features
