All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified.
Input bias currents of a FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive as shown in
Figure 18. Pulse techniques must be used that will maintain the junction temperatures as close to the ambient temperature as is possible.
