AH49FQ

Transferring Characteristics (@VCC = 5V)

When there is no external magnetic field (B=0Gauss), the quiescent output voltage is one-half the supply voltage in general.

In the AH49FQ, the die is placed underneath the lead frame and therefore when a magnet pole approaches the SC59 part marking surface, 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.
