A3517

Data Sheet 27501.11B 3517 AND 3518 RATIOMETRIC, LINEAR HALL-EFFECT SENSOR ICS FOR HIGH-TEMPERATURE OPERATION The A3517xUA and A3518xUA are sensitive, temperature-stable linear Hall-effect sensor ICs with greatly improved offset characteristics. Ratiometric, linear Hall-effect devices 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 devices 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 VCC Characteristics table for complete, individual device parametrics.
