Hi guys,
I have a question as I am not sure I am looking at this the correct way....
I have been using a resistor array in a precision instrumentation amplifier which has an abs. tolerance of 0.1% and a ratio tolerance of 0.05%. I can't get these anymore and I can't change the layout of the board so I am thinking of using two single resistors.
I have found one that has a tolerance of 0.05% and I would like to know if I use two of these resistors in place of the network, would the effective tolerance ratio just be the actual tolerance of 0.05% or if there is another calculation I would need to do, to define a ratio tolerance? If so, what would that calculation be?
