General Description
The OH49F is a small, versatile linear Hall-effectdevice 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. It also includes precision resistors to provide increased temperature
stability and accuracy. The operating temperature range of these linear Hall sensors is
-40℃ to105℃, appropriate for commercial, consumer and industrial applications.

LINEAR HALL-EFFECT IC
Transfer Characteristics (VCC=5V)
When there is no ouside magnetic field (B=0GS),
the quiescent output voltage is one-half the supply
voltage in general. If a south magnetic pole
approches to the front face (the side with marking
ID) of the Halleffect sensor, the circuit will drive the
output voltage higher. Contrary, a north magnetic
pole will drive the output voltage lower. The
variations of voltage level up or down are
symmetrical. Greatest magnetic sensitivity is
obtained with a supply voltage of 6V, but at the cost of increased supply current and a
slight loss of output symmetry. So, it is not recommended to work in such condition unless
the output voltage magnitude is a main issue. The output signal can be capacitively
coupled to an amplifier for boosting further if the changing frequency of the magnetic field
is high.
