1 The input stage uses PNP transistors; therefore, input bias current always flows into the part.
2 The values specified for G > 1 do not include the effects of the external gain-setting resistor, RG.
3 Input voltage range of the AD8426 input stage. The input range depends on the common-mode voltage, the differential voltage, the gain, and the reference voltage.
