Input bias currents of an FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive, as shown in
Figure 4. Pulse techniques must be used that will maintain the junction temperature as close to the ambient temperature as possible.
All characteristics are measured under open-loop conditions with zero common-mode voltage, unless otherwise specified. Full range is
TA = −55°C to 125°C.
