This article is a technical document of Allegro’s Hall effect sensor integrated circuits, how these devices were built, and how Allegro use the Hall effect principle to develop these devices. It ...

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 ...

The ATS682LSH from Allegro MicroSystems is a Hall-effect sensing integrated circuit and magnet combination that is intended for true zero-speed sensing of ferrous targets in two-wire applications. The ...

Allegro Microsystems has introduced isolated differential current sensor ICs based on the Hall effect. Accuracy is typically +/-1% from 25 to 125°C, and +/-3% from -40 to +25°C. Both the ACS724KMA ...

Allegro MicroSystems Inc. announces an open loop Hall-effect sensor IC with near closed loop performance in accuracy and bandwidth. Allegro MicroSystems Inc. announces an open loop Hall-effect sensor ...

Abstract: The spinning current modulation technique is shown not only to be able to suppress all the offset and low-frequency noise contributions from the Hall sensing element and its preamplifier, ...

Allegro MicroSystems' two high-performance, low-noise 2100-Vrms isolation current sensors, the ACS712 and ACS713, provide lower noise and higher accuracy than previous generation current sensors.

Abstract: In this paper, a switch-mode CMOS Hall sensor circuit is designed, which used the quadrature current method and chopper stabilization technique to eliminate the offset voltage from the Hall ...
