A1389 - Allegro

A1389 Linear Hall-Effect Sensor IC

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 package.
