Product Introduction

Overview

The DRV5055A2QLPG is a linear Hall effect sensor produced by Texas Instruments. This device responds 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 changes linearly with the applied magnetic flux density. The sensor features a ratiometric architecture, which helps eliminate errors due to VCC tolerance when used with an external analog-to-digital converter (ADC) that uses the same VCC for its reference. Additionally, the device includes magnet temperature compensation to ensure linear performance across a wide temperature range of –40°C to 125°C.
