NOTES
1Input offset voltage specifications are guaranteed after 5 minutes of operation at T A = +25°C.
2Bias current specifications are guaranteed maximum at either input after 5 minutes of operation at TA = +25°C. For higher temperature, the current doubles every 10°C.
3Gain = –1, RLOAD = 2 kΩ.
4Defined as the time required for the amplifier’s output to return to normal operation after removal of a 50% overload from the amplifier input.
5Defined as the maximum continuous voltage between the inputs such that neither input exceeds ± 10 V from ground.
All min and max specifications are guaranteed.
Specifications subject to change without notice.
