Description

The ADAU1860/ADAU1860-1 are codecs with three inputs and one output that incorporate two digital signal processors (DSPs). The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise canceling earphones. With the addition of just a few passive components, the ADAU1860/ADAU1860-1 provide a complete earphone solution.APPLICATIONSNoise canceling handsets, headsets, and headphonesBluetooth active noise canceling (ANC) handsets, headsets, and headphonesPersonal navigation devicesDigital still and video camerasMusical instrument effect processorsMultimedia speaker systemsSmartphones
