Overview

New applications for linear output Hall-effect sensors-such as displacement and angular position-require higher accuracy and smaller package sizes. The Allegro A1388 and A1389 linear Hall-effect sensor ICs have been designed specifically to meet both requirements.

  • 5.0 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
  • Undervoltage lockout (UVLO)
  • Wide ambient temperature range: -40°C to 150°C
