Product Introduction

Overview

The ADAU1401AWBSTZ-RL, produced by Analog Devices Inc., is a comprehensive single-chip audio system that integrates a 28-/56-bit audio DSP, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and microcontroller-like control interfaces. This chip is designed to provide advanced audio signal processing capabilities, comparable to those found in high-end studio equipment. It supports a wide range of audio processing functions, including equalization, cross-over, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening. The ADAU1401A is fully programmable using the SigmaStudio software, allowing users to configure custom signal processing flows graphically.
