... VCC Hall Element Regulator SLEEP 1391-DS, Rev. 2 A1391, A1392, A1393, and A1395 Description 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 Hall effect transducer element inside the ICs ...
