A1309 - Linear Hall-Effect Sensor

This page provides the datasheet information for the A1309, a member of the A1308 Linear Hall-Effect Sensor family.

Description

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

The Allegro A1308 and A1309 linear Hall-effect sensor ICs have been designed specifically to meet both requirements.

Features

  • 5 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.
