AH49F LINEAR HALL EFFECT IC Description Pin Assignments The AH49F is a small, versatile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The output voltage is set by the supply voltage and (Top View) (Front View) varies in proportion to the strength of the magnetic field. GND 3 The integrated circuitry features low noise output, which makes it unnecessary to use external filtering components. It also includes OUT 3 precision resistors to provide increased temperature stability and 2 GND accuracy. The operating temperature range of these linear Hall 1 VCC 1 2 sensors is -40C to +105C, appropriate for commercial, consumer, and industrial environments. VCC OUT TO92S (Type A) SC59 The AH49F is available in standard TO92S (Type A), SC59 and U- DFN2020-6 (Type C) packages.
