A1185 Datasheet | Allegro MicroSystems

A1185 and A1186 Ultrasensitive Two-Wire Field-Programmable Chopper-Stabilized Unipolar Hall-Effect Switches The A1185 and A1186 are ultrasensitive, two-wire, unipolar Hall effect switches. The operate point, BOP, can be field-programmed, after final packaging of the sensor and placement into the application. This advanced feature allows the optimization of the sensor switching performance, by effectively accounting for variations caused by mounting tolerances for the device and the target magnet. This family of devices are produced on the Allegro MicroSystems new DABIC5 BiCMOS wafer fabrication process, which implements a patented, high-frequency, chopper-stabilization technique that...
