00 — Overview

What the ES7210 does

The ES7210 is a high-performance, four-channel audio analog-to-digital converter utilizing multi-bit delta-sigma modulation. This device supports sampling frequencies from 8 to 100 kHz with a 24-bit resolution, achieving a signal-to-noise ratio of 102 dB and a THD+N of -85 dB. It features four independent microphone inputs with dedicated bias pins and supports standard audio, USB, and non-standard clock modes. The ES7210 operates in master or slave serial data port configurations and includes a low-power standby mode. Typically used in smart speakers and mic array applications for far-field voice capture, the component requires an I2C interface for micro-controller configuration and a QFN-32 package.
