Overview

The DRV5055A1QLPGM is a ratiometric linear Hall effect sensor designed for precise magnetic field measurement. It provides an analog voltage output that is proportional to the magnetic field, with a quiescent offset at Vcc/2. This sensor features temperature compensation for magnet drift and a fast 20 kHz sensing bandwidth.

Why Choose This Part

This sensor offers excellent accuracy across its full operating temperature range of -40 degrees C to 125 degrees C due to its integrated temperature compensation. Its 20 kHz bandwidth allows for dynamic measurements, and the low-noise analog output simplifies signal conditioning. The ability to operate from a 3V to 5.5V supply makes it versatile for different system voltages.

Applications

Precise Position Sensing
Ideal for applications requiring accurate determination of linear or angular position, such as joysticks, pedals, and robotic joints.
Industrial Automation
Suitable for automation systems for tasks like end-of-travel detection, object counting, and liquid level measurement in harsh industrial environments.
Home Appliances
Can be integrated into appliances for control feedback, knob position sensing, or door open/closed detection.
Absolute Angle Encoding
Used in conjunction with a magnet for non-contact absolute angle measurement in rotational systems.
Current Sensing
Enables non-contact current measurement by sensing the magnetic field generated by current flowing through a conductor.
Medical Devices
Applicable in various medical instruments for motion sensing, fluid flow detection, and precise control interfaces.
