All characteristics are measured under open-loop conditions with zero common-mode 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 17. Pulse techniques must be used that maintain the junction temperature as close to the ambient temperature as possible.
