NOTES: (1) Overall difference amplifier configuration. Referred to input pins (V
+ and V
–), gain = 0.1V/V. Specified with 10k
in feedback of A2. (2) Input offset
voltage specification includes effects of amplifier’s input bias and offset currents. (3) Common-mode voltage range is 11 (V–) to 11 [(V+) – 1] with a maximum of
±
100V.
(4) Includes effects of input current noise and thermal noise contribution of resistor network.
