Hello,
I am trying to use a 10K pot to adjust a dual voltage range.
Lets say I have a -1VDC at pin.1 and 1VDC at pin.3, in this case I can get any voltage between +/-VDC on Pin.2 - the drop over Pot resistance (correct?)
My primary input voltage is +/-5VDC, I would like to have the user able to adjust his range rather than a fixed +/-1VDC using fixed value resistors at pin1&3. This can be accomplished by adding two more pots on both pins 1&3. But I am not sure how to calculate the value of the pots I need to use.
Can someone suggest me how I can achieve this?
thanks.
