¹The input stage uses pnp transistors, so input bias current always flows into the part.

²At high gains, the part is bandwidth limited rather than slew rate limited.

³For G > 5, gain error specifications do not include the effects of External Resistor R_G.

⁴Input voltage range of the AD8227 input stage. The input range depends on the common-mode voltage, differential voltage, gain, and reference voltage. See the

Input Voltage Range section for more information.
