Product Introduction

Overview

The ISO7741DBQEVM is an evaluation module designed by Texas Instruments to facilitate the evaluation and development of the ISO7741 high-performance, quad-channel digital isolator. This module is part of the ISO774x family, which includes devices with reinforced insulation ratings and high electromagnetic immunity. The ISO7741DBQEVM allows designers to assess the performance of the ISO7741 device with minimal external components, making it an essential tool for fast development and analysis of isolated systems.
