Need a Hall sensor? A strip of copper, a strong magnet, and an LM358 are all you need to explore the Hall effect hands-on.

This application note presents some of the fundamental information about Hall-Effect sensors. It also presents the basics of magnetics, and the added value of programmable sensors and sensor interface ...

This document presents an application guide of Hall-Effect integrated circuits (ICs). It covers low-cost simplified switching, low-cost linear sensor ICs, sensitive circuits for rugged service, linear ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

Allegro MicroSystems Europe has introduced a new high-speed, low-noise Hall-effect current sensor which offers 3 kV RMS voltage isolation and a low-resistance current conductor for 50-100 A current ...

Allegro MicroSystems, Inc. announces a new current sensor IC that provides an economical and precise solution for AC or DC current sensing in 3.3 V supply applications. This new device is targeted at ...

A high-current/high-temperature linear Hall-effect current sensor IC has been optimised for 3.3 V operation by Allegro MicroSystems. The ACS759 device consists of a ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

We have developed a high-precision linear Hall sensor, which can detect absolute angles from 0 to 360°. In this sensor, novel vertical Hall elements have been used that can be fabricated using CMOS ...
