Product Introduction

Overview

The DRV5055A1QLPG is a ratiometric linear Hall effect sensor produced by Texas Instruments. This device is designed to respond proportionally to magnetic flux density, making it suitable for accurate position sensing in a wide range of applications. It operates from either 3.3-V or 5-V power supplies and provides an analog output that is referenced to VCC. The sensor features a ratiometric architecture, which helps eliminate errors from VCC tolerance, and includes temperature compensation to maintain linear performance across a temperature range of –40°C to 125°C.
