A3245 - Chopper-Stabilized Omnipolar Hall-Effect Switches

Download the A3245 datasheet PDF. This datasheet also covers the A3245_Allegro variant, as both devices belong to the same chopper-stabilized omnipolar hall-effect switches family and are provided as variant models within a single manufacturer datasheet.

General Description

The A3245 integrated circuit is an omnipolar, ultrasensitive Hall-effect switch with a digital output.

This sensor has an integrated regulator permitting operation to 24 V, making it the first omnipolar switch available for operation to 24 V.

Key Features
