RATIOMETRIC, LINEAR HALL-EFFECT SENSORS FOR HIGH-TEMPERATURE OPERATION

The A3515– and A3516– 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 A3515– features an output sensitivity of 5 mV/G, while the A3516– has an output sensitivity of 2.5 mV/G. See the Magnetic Characteristics table for

complete, individual device parametrics.
