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° to +105° appropriate for commercial, consumer,
C
C,
and industrial environments.
The AH49F is available in standard TO92S (Type A), SC59 and U-
DFN2020-6 (Type C) packages.

Transferring Characteristics
(@V
CC
= 5V)
When there is no external magnetic field (B=0Gauss), the quiescent output voltage is one-half the supply voltage in general.
For TO92S (Type A) and U-DFN2020-6 (Type C) packages, if a South magnetic pole approaches the part marking surface (the side with part
marking ID) of the Hall effect sensor, the circuit will drive the output voltage higher. In contrary, a North magnetic pole will drive the output voltage
lower. The variations of voltage level up or down from the quiescent output voltage (the null voltage) are symmetrical and proportional to the
magnetic flux density. In the SC59, the die is placed underneath the lead frame and therefore when a magnet pole approaches the SC59 part
marking surface, the direction of the magnetic field in to the die is reversed compared to TO92S (Type A). This results in a reverse response to
the magnetic flux density in SC59 package compared with TO92S (Type A) and U-DFN2020-6 (Type C) packages. (i.e. if the reverse magnetic
pole approaches the part marking surface of SC59, the output is the same as TO92S (Type A) package.) The largest magnetic sensitivity is
obtained with a supply voltage of 8V, 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 a next-level amplifier
for further amplifying if the changing frequency of the magnetic field is high.
