General Description
The OH49E 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. It also includes precision resistors to provide increased temperature
stability and accuracy. The operating temperature range of these linear Hall sensors is
-20to100, appropriate for commercial, consumer and industrial applications.
Features
· Miniature Construction
· Power Consumption of 4.2mA at VCC=5V for Energy Efficiency
· Single Current Sourcing Output
· Linear Output for Circuit Design Flexibility
· Low Noise Output Virtually Eliminates the Need for Filtering
· A Stable and Accurate Output
· Temperature Range of -20to 100
· Responds to Either Positive or Negative Gauss
Typical applications

Transfer Characteristics (VCC=5V)
When there is no outside magnetic field (B=0GS),
the quiescent output voltage is one-half the supply
voltage in general. If a south magnetic pole
approaches to the front face (the side with marking
ID) of the Hall effect 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 5V, 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.
