All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified. Full range for
the µA741C is 0°C to 70°C, the µA741I is –40°C to 85°C, and the µA741M is –55°C to 125°C.
NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
