ALLEGRO MICROSYSTEMS A1395SEHLT-T

The A1395SEHLT-T is a 3V micro power linear Hall Effect Sensor IC with tri-state output and user-selectable sleep mode. It provides a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity is directly proportional to the current flowing through the hall effect transducer element inside the IC. In many applications, it is difficult to achieve sufficient sensitivity levels with a hall effect sensor IC without consuming more than 3mA of current. Each BiCMOS monolithic circuit integrates a hall element, improved temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the hall element, a small-signal high-gain amplifier and proprietary dynamic offset cancellation circuits. End of line, post-packaging, factory programming allows precise control of device sensitivity and offset.
