Overview
The ADAU1860BCBZRL, produced by Analog Devices Inc., is a highly advanced audio codec integrated with two digital signal processors (DSPs). This component is designed to provide a comprehensive audio processing solution, particularly optimized for low-latency applications such as noise canceling earphones, headsets, and headphones. The ADAU1860 features a programmable FastDSP audio processing engine, supporting up to 768 kHz sample rates, and includes biquad filters, limiters, volume controls, and mixing capabilities. The Tensilica HiFi 3z DSP core at its heart enables robust and flexible audio processing.
