A1388 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. These temperature-stable devices are available in both surface-mount and through-hole packages.
