3518 Ratiometric / Linear Hall-effect Sensors

3517 AND 3518 RATIOMETRIC, LINEAR HALL-EFFECT SENSORS FOR HIGH-TEMPERATURE OPERATION The A3517xUA and A3518xUA are sensitive, temperature-stable linear Hall-effect sensors with greatly improved offset characteristics. Ratiometric, linear Hall-effect sensors provide a voltage output that is proportional to the applied magnetic field and have a quiescent output voltage that is approximately 50% of the supply voltage. These magnetic sensors are ideal for use in linear and rotary position sensing s.

3518 Features

* an output sensitivity of 5 mV/G while the A3518xUA has an output sensitivity of 2.5 mV/G. See the Magnetic Characteristics table for complete, individual device parametrics. Each BiCMOS monolithic circuit integrates a Hall element, improved temperature-compensating circuitry to reduce the intrinsic
