Operation at a nominal supply voltage slightly less than ±12 V is recommended to allow for power supply tolerances. 2 Does not include effects of external resistor, RG. 3 Total input range depends on common-mode voltage, differential voltage, and gain. See Figure 18 through Figure 21 and the Input Voltage Range section in the Theory of Operation section for more information.
