Note 3:
Slew rate is measured between
±
10V on an output swing of
±
12V
on
±
15V supplies, and
±
2V on an output swing of
±
3.5V on
±
5V supplies.
Note 4:
Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2
π
Vp.
Note 1:
A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2:
Input offset voltage is tested with automated test equipment
in <1 second.
