A1423 Datasheet High Precision Hall Effect AC-coupled Differential Sensor

Manufacturer: Allegro MicroSystems

Overview: A1421, A1422, and A1423 High Precision Hall-Effect AC-Coupled Differential Sensor IC with Integrated Filter.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The A1421, A1422, and A1423 are AC-coupled Hall-effect sensor ICs which include monolithic integrated circuits that switch in response to changing differential magnetic fields created by rotating ring magnets or, when coupled with a magnet, by ferrous targets.

This family of devices also includes an integrated capacitor that provides the high accuracy of analog sensing without an external filter capacitor.

This reduces cost and ponents, while improving the reliability of the final sensor solution.

Key Features

  • Integrated tracking capacitor.
  • Used for sensing motion of ring magnet or ferrous targets.
  • Wide operating temperature range.
  • Operation with magnetic input signal frequency from 20 Hz to 30 kHz.
  • EMI/ESD-resistant.
  • Large effective air gaps.
  • 4.0 to 26.5 V supply operating range.
  • Output compatible with CMOS logic families.
  • Reverse battery protection.
  • Resistant to mechanical and thermal stress.
  • Accurate.
