ADI ADAU1860BCBZRL

The ADAU1860 is a codec with three inputs and one output that incorporates 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 earphone. With the addition of just a few passive components, the ADAU1860 provides a complete earphone solution.
