(1)

Input voltage range of the instrumentation amplifier input stage. The input range depends on the common-mode voltage, differential

voltage, gain, and reference voltage. See Typical Characteristic curves.

(2)

The values specified for G > 5 do not include the effects of the external gain-setting resistor, RG.
