A1381 (A1381 - A1384) Programmable Linear Hall Effect Sensors

New applications for linear output Hall effect sensors, such as displacement, angular position, and current measurement, require high accuracy in conjunction with small package size. The Allegro® A138x family of programmable linear Hall effect sensors was designed specifically to achieve both goals..

A1381 Features

* ▪ Customer programmable offset, sensitivity, sensitivity temperature coefficient, and polarity ▪ Programmability at end-of-line ▪ Ratiometric sensitivity, quiescent voltage output, and clamps for interfacing with application DAC ▪ Temperature-stable quiescent voltage output and sensitivity ▪ Precise
