3507中文资料ALLEGRO数据手册PDF规格书

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 -40°C and +150°C. The two devices are similar except for temperature stability over the operating temperature range. See the Magnetic Characteristics table for complete, individual device parametrics.
