3. Hall Amplifier Input Block
The hall current (I
H
) is determined by R1, R2 and R3.
Where, the R2 is the impedance of hall sensor.
An external capacitor, C1, can be used to reduce a power supply noise. In addition, C2 is to remove a noise which is caused in
case the line is long from the hall sensor output to the hall input (pin 5 / 6) of the device.
The input bias voltage of hall amplifier is between 1V and V
CC
-2V as following figure.
It is recommended that R1 and R3 should have the same value to make the output signal of hall sensor centered as V
CC
/2.
