BCD Semiconductor Manufacturing Limited AH49H
The AH49H 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 varies in proportion to the strength of the magnetic field. The integrated circuitry features low noise output, which makes it unnecessary to use external filtering components.GENERAL DESCRIPTION
It also includes precision resistors to provide increased temperature stability and accuracy. The operating temperature range of these linear Hall sensors is -40°C to 105°C, appropriate for commercial, consumer, and industrial environments. The AH49H is available in standard TO-92S-3 and SOT-23-3 packages.FEATURES
