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
