NOTES: (1) Overall difference amplifier configuration. Referred to input pins (VIN+ and VIN–), gain = 0.1V/V. Specified with 10kΩ in feedback of A2. (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. (4) Common-mode voltage range is 11 (V–) to 11 [(V+) – 1] with a maximum of ±100V.
