Product Introduction

Overview

The ISOSD61TR, produced by STMicroelectronics, is a galvanic isolated second-order Sigma-Delta modulator. It utilizes embedded transformer coupling technology to convert an analog input signal into a high-speed, 25 Msps, 1-bit digital data stream. The modulator is isolated from the digital I/O section through high-speed isolated data coupling, offering superior performance compared to other isolated transceivers like optocouplers. This component is designed for high accuracy and reliability in various industrial applications.
