A31004 Datasheet Unidirectional Linear Hall-effect Sensor

Manufacturer: Allegro MicroSystems

Overview: A31004 Unidirectional Linear Hall-Effect Sensor IC with Analog Output in Miniature Low-Profile Surface-Mount.

General Description

New applications for linear output Hall-effect sensors, such as displacement and angular position, require higher accuracy and smaller package sizes.

The Allegro A31004 linear Halleffect sensor IC has been designed specifically to meet both requirements.

The accuracy of this device is enhanced via end-of-line optimization.

Key Features

  • 3.3 V supply operation.
  • QVO temperature coefficient programmed at Allegro™ for improved accuracy.
  • Miniature package options.
  • High-bandwidth, low-noise analog output.
  • High-speed chopping scheme minimizes QVO drift across operating temperature range.
  • Temperature-stable quiescent voltage output and sensitivity.
  • Precise recoverability after temperature cycling.
  • Output voltage clamps provide short-circuit diagnostic capabilities.
