Product Details

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.


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