Product Introduction

Overview

The ADAU1772BCPZ, produced by Analog Devices Inc., is a highly integrated audio codec designed for a variety of audio applications. This codec features four analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs), along with a robust digital signal processing (DSP) engine. The DSP core is capable of performing advanced functions such as filtering, level control, signal level monitoring, and mixing. The device is optimized for low latency, making it ideal for noise-cancelling headsets and other real-time audio processing applications.
