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.

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/2πVp.
