Note 5. All characteristics are measured under open–loop conditions with zero common–mode volt-

age unless otherwise specified.

Note 6. Input bias currents of a FET–input operational amplifier are normal junction reverse currents,

which are temperature sensitive. Pulse techniques must be used that will maintain the junc-

tion temperatures as close to the ambient temperature as is possible.
