(1)

Long-term input offset voltage stability refers to the averaged trend line of VOS vs time over extended periods after the first 30 days of

operation. Excluding the initial hour of operation, changes in VOS during the first 30 operating days are typically less than 2 μV.

Specified by characterization.

(3)

Sample tested.

(4)

Specified CMRR test condition.

(5)

Specified by design.

(6)

To maintain high open-loop gain throughout the ±10-V output range, AOL is tested at –10 V ≤ VO ≤ 0 V, 0 V ≤ VO ≤ +10 V, and –10 V ≤

VO ≤ +10 V.
