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.

FEATURES
■ Temperature-Stable Quiescent Output Voltage
■ Precise Recoverability After Temperature Cycling
■ Output Voltage Proportional to Applied Magnetic Field
■ Ratiometric Rail-to-Rail Output
■ Improved Sensitivity
■ 4.5 V to 5.5 V Operation
■ Immune to Mechanical Stress
■ Small Package Size
■ Solid-State Reliability
