(1) All characteristics are measured under open-loop conditions with zero common-mode voltage, unless otherwise specified.
(2) Full range for TA is –40°C to 85°C for I-suffix devices and –40°C to 125°C for Q-suffix devices.
(3) Input bias currents of an FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive, as
shown in Figure 14. Pulse techniques must be used that maintain the junction temperature as close to the ambient temperature as
possible.
