1
Input offset voltage specifications are guaranteed after 5 minutes of operation at T
A
= 25°C.
2
Bias current specifications are guaranteed maximum at either input after 5 minutes of operation at T
A
= 25°C. For higher temperatures, the current doubles every 10°C.
3
Defined as voltage between inputs, such that neither exceeds ±10 V from ground.
4
Typically exceeding −14.1 V negative common-mode voltage on either input results in an output phase reversal.
