ALS31001: Linear Hall-Effect Sensor IC with Analog Output, in Ultramini Through-Hole Package

Allegro 3-Pin SIP UA Package


Top Features


The ALS31001LUAA device is a miniature programmable linear Hall-effect sensor IC that operates at 3.3 V.

This device is an ideal solution for use in automotive and industrial applications requiring high accuracy and operation across an extended temperature range, –40°C to 150°C.

Target applications include:

  • Anti-tamper for metering applications
  • EPS - Torque sensing
  • EPS - Angle sensing (2 devices are used, rotated 90° relative to each other
  • Transmission - for position sensing
  • QVO temperature coefficient programmed at Allegro for improved accuracy
  • 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
