mA 1 Input offset voltage specifications are guaranteed after 5 minutes of operation at TA = 25°C. 2 Bias current specifications are guaranteed maximum at either input after 5 minutes of operation at TA = 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.
