6.1.3 Input Bias Current

Figure 5-5 shows that the input bias current of the OPAx130 is approximately 5pA at room temperature and increases with temperature.

Input stage cascode circuitry allows the input bias current to remain virtually unchanged throughout the full input common-mode range of the OPAx130. See also Figure 5-6.
