NOTES: (1) Overall difference amplifier configuration. Referred to input pins (VI+N and VI–N), gain = 1V/V (2) Input offset voltage specification includes effects of
amplifier's input bias and offset currents. (3) Includes effects of input current noise and thermal noise contribution of resistor network.
