A1392 General Description

These 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. 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 A1391 and A1392 minimize current consumption to less than 25 A through the addition of a user-selectable sleep mode. This makes these devices per- fect for battery-operated applications such as: cellular phones, digital cameras, and portable tools. End users can control the current consumption of the A1391 and A1392 by applying a logic level signal to the SLEEP pin. The outputs of the devices are not valid (high-imped- ance mode) during sleep mode. The high-impedance output feature allows the connection of multiple A1391 and A1392 Hall effect devices to a single A-to-D converter input.

The quiescent output voltage of these devices is 50 % nominal of the ratiometric supply reference voltage applied to the VREF pin of the device. The output voltage of the device is not ratiometric with respect to the SUPPLY pin.
