The A3507 and A3508 are sensitive, temperature-stable linear Hall-effect sensors. 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 -40C and +150C. The two devices are similar except for temperature stability over the operating temperature range. See the Magnetic Characteristics table for complete, individual device parametrics.
