AH49F
LINEAR HALL EFFECT IC
Description
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
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. 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 AH49F is available in standard TO-92S, SC59 and U-DFN2020-6
packages.
