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.
