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 k, then an
offset of 9 mV will be developed (VOS=IBx RF).Using a compensation resistor (RC), as shown in Figure 37,
cancels out this affect. But the input offset current (IOS) will still contribute to an offset voltage in the same
manner - typically 0.05 mV at room temp.
