3515 Datasheet Ratiometric/ Linear Hall-effect Sensors For High-temperature Operation

Manufacturer: Allegro MicroSystems

Overview: 3515 3516 AND RATIOMETRIC, LINEAR HALL-EFFECT SENSORS FOR HIGH-TEMPERATURE OPERATION The A3515– and A3516– are sensitive, temperature-stable linear Halleffect 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.

Key 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. Each BiCMOS monolithic circuit integrates a Hall element, improved temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element, a small-signal high-gain amplifier, and a rail-to-rail lowimpedance output stage. A proprietary dynamic offset cancelation technique, with an internal hig.
