Hall effect sensor amplifier connectio?

Hi to all...
I am using a unipolar linear hall effect sensor to measure my car's rpm from the cranksaft pulley where the engine's sensor measuring the rpm. So the hall sensor needs to put north pollar magnet to the pulley but it is not possible so I want to take the triger from the tooths that ob the pulley. I have found that
But it needs an amplifier.
Does someone knows how to connect the amplifier?

Connect the Amplifier to the Output Pin.

You haven't provided the part number or datasheet for your device - that's necessary...

That is both the sensor and the amplifier.
