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 T
A = +25°C. For higher temperature, the current doubles every 10°C.
3Defined as voltages between inputs, such that neither exceeds
±10 V from ground.
Specifications subject to change without notice.
(@ +25 C and VS =
15 V dc unless otherwise noted)
