for use in high-temperature applications. This device uses a patented high

frequency chopper-stabilization technique on Allegro's new DABIC5

BiCMOS wafer fabrication process to achieve magnetic stability and to

eliminate offset inherent in single-element devices and from harsh-

application environments.

programming is performed after final packaging of the sensor and

placement of the Single In-Line Package (SIP) into the application. This

advanced feature allows for optimization of sensor switching performance

by effectively accounting for variations caused by magnet and SIP

placement tolerances.

field and will switch LOW with the removal of the field. The A1180/2 has

the opposite polarity as the others, switching LOW in the presence of a

sufficient magnetic field and HIGH with the removal of the field.
