Linear Hall-Effect Sensor Ics, A1395SEHLT-T, Allegro
The A1395SEHLT-T linear Hall-effect sensor integrated circuit (IC) provides a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of a typical Hall-effect IC (measured in mV/G) 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 3 mA of current. The A1395SEHLT-T minimizes current consumption to less than 25 µA through the addition of a user-selectable sleep mode. This makes the device perfect for battery-operated applications such as cellular phones, digital cameras, and portable tools.
