Data Sheet LINEAR HALL-EFFECT IC AH49E General Description Features The AH49E is a small, versatile linear Hall-effect Miniature Construction device that is operated by the magnetic field from a Power Consumption of 3.5mA at V =5V for CC permanent magnet or an electromagnet. The output Energy Efficiency voltage is set by the supply voltage and varies in pro- Single Current Sourcing Output portion to the strength of the magnetic field. Linear Output for Circuit Design Flexibility Low Noise Output Virtually Eliminates the Need The integrated circuitry features low noise output, for Filtering which makes it unnecessary to use external filtering. It A Stable and Accurate Output also includes precision resistors to provide increased o o temperature stability and accuracy. The operating tem- Temperature Range of -40 C to 85 C o Responds to Either Positive or Negative Gauss perature range of these linear Hall sensors is -40 C to o 85 C, appropriate for commercial, consumer and industrial applications. Applications The AH49E is available in standard TO-92S and SOT- 23-3 packages.
