A1359 - Factory-Programmed Dual Output Linear Hall-Effect Sensor

General Description

New applications for linear output Hall-effect sensors, such as displacement and angular position, require high accuracy in conjunction with redundant outputs.

The Allegro A1359 programmable, linear, Hall effect sensor IC has been designed specifically to achieve both goals.

Key Features

  • Dual tracking outputs: analog voltage output and pulsewidth-modulated (PWM) output.
  • Matched analog and PWM outputs enable user to detect various output error conditions.
  • Factory-programmed offset, sensitivity, and polarity.
  • Sensitivity temperature coefficient (TC) and QVO/QD temperature coefficient programmed at Allegro™ for improved accuracy.
  • High-speed chopping scheme minimizes quiescent voltage output (QVO) drift across temperature.
  • Tempe.
