3. Hall Amplifier Input Block

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.
