NOTES
1
Long-Term Input Offset Voltage Stability refers to the averaged trend line of V
OS
vs. time over extended periods after the first 30 days of operation. Excluding the ini-
tial hour of operation, changes in V
OS
during the first 30 operating days are typically less than 2.0 µV.
2
Sample tested.
3
Guaranteed by design.
4
Guaranteed by CMRR test condition.
5
To insure high open-loop gain throughout the ±10 V output range, A
VO
is tested at –10 V ≤ V
O
≤ 0 V, 0 V ≤ V
O
≤ +10 V, and –10 V ≤ V
O
≤ +10 V.
