Introduction

The ADAU1788 is a codec with two 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 cancelling headsets. With the addition of just a few passive components, the ADAU1788 provides a noise cancelling headphone solution.
