Description

The A1102EUA is a magnetic switch that belongs to the Allegro A110x family of Hall-effect switches. This family of devices is designed to replace the popular Allegro 312x and 314x lines of unipolar switches. The A110x family is manufactured using BiCMOS technology and offers fast power-on time and low-noise operation. The switchpoint accuracy is increased by performing device programming after packaging to eliminate offsets that can be induced by package stress. The unique Hall element geometries and low offset amplifiers minimize noise and reduce the residual offset voltage caused by device overmolding, temperature excursions, and thermal stress.
