(1) Relation of RG1 / RIN1 or RG2 / RIN2 to nominal ratio.
(2) Relation of RG1, RIN1, RG2, or RIN2 to nominal resistance.
(3) The specification is the result of this expression, given as a percentage (multiplied by 100%).
(4) Specified by characterization.
(5) The specification is the calculated CMRR when implemented in a difference amplifier configuration with an ideal op-amp, such that the only source of common-mode error is the resistor network. See the Optimizing CMRR in Differential Amplifier Circuits With Precision Matched Resistor Divider Pairs application note for more information. Effects over frequency are not included. If the circuit is configured in an attenuating gain, this result changes accordingly.
