† All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified.
‡ Full range for uA747C is 0
°C to 70°C and for uA747M is –55°C to 125°C.
*On products compliant to MIL-STD-883, Class B, this parameter is not production tested.
NOTE 5: This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback.
