A1391 Micropower 3V Linear Hall-Effect Sensor

The A139x family of linear Hall-effect sensor integrated circuits (ICs) provide a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of typical Hall-effect ICs (measured in mV/G) is directly proportional to the current flowing through the.
