ADAU1777BCBZRL

ADAU1777 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 analogue input to the DSP core to the analogue 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, this device provides a complete headset solution. It is widely used in application such as noise cancelling handsets, headsets, and headphones, Bluetooth® active noise cancelling (ANC) handsets, headsets, and headphones, personal navigation devices, digital still and video cameras etc.
