Unity-Gain Frequency vs Common Mode Voltage for Various Loads UNITY GAIN PULSE RESPONSE CONSIDERATION A pull-up resistor is well suited for increasing unity-gain, pulse response stability. For example, a 600 Ω pull-up resistor reduces the overshoot voltage by about 50%, when driving a 220 pF load.

Pulse Response per Figure 35 INPUT BIAS CURRENT CONSIDERATION Input bias current (IB) can develop a somewhat significant offset voltage. This offset is primarily due to IB flowing through the negative feedback resistor, RF. For example, if IB is 90 nA (max @ room) and RF is 100 kΩ, then an offset of 9 mV will be developed (VOS=IBx RF).
