Because maximum supply voltage is 24 V between the negative and positive supply, these specifications at ±12V are at the part’s limit. Operation at a nominal supply
voltage slightly less than ±12 V is recommended to allow for power supply tolerances.

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.
