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 systems in the harsh environments of automotive and industrial applications over extended temperatures to -40°C and +150°C. The A3517xUA 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.
