† 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 17. Pulse techniques must be used that maintain the junction temperatures as close to the ambient temperature as possible.
