The is a micro-power Linear Hall Effect Sensor with tri-state output and user-selectable sleep mode. IC provides a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of typical Hall-effect ICs is directly proportional to the current flowing through the Hall-effect transducer element inside the ICs. The high-impedance output feature allows the connection of multiple A139x Hall effect devices to a single A-to-D converter input. The quiescent output voltage of these devices is 50% nominal of the ratio-metric supply reference voltage applied to the VREF pin of the device. The output voltage of the device is not ratio-metric with respect to the SUPPLY pin.
