A1326 - Allegro MicroSystems

A1326 Low-Noise Linear Hall-Effect Sensor

New applications for linear output Hall-effect devices, such as displacement, angular position, and current measurement, require high accuracy in conjunction with small package size. The Allegro™ A1324, A1325, and A1326 linear Hall-effect sensor ICs are designed specifically to achieve both goals. This temperature-stable device is available in a miniature su.
