ADAU1850BCBZRL

ADAU1850 is a codec with three inputs and one output that incorporates one digital signal processor. 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 earphones. With the addition of a few passive components, the 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, musical instrument effect processors, multimedia speaker systems, smartphones etc.
