i will try to keep this brief..
i am using a hall sensor, analogue output, reacts to both north and south poles of the magnet, and therefore, in its "idle" state, the output voltage is 1.65V, i need to remove this, and amplify the voltage.
I.E.:
I am only using one pole of the magnet with the hall sensor, therefore, the voltage will always be between 1.65 - 3.3V (ish) what i want to do, is take that 1.65V signal, remove the dc bias, and amplify it so that the signal i get out is between 0 and 3.3V.
hope this makes sense
ask if it doesnt!
