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
πVp.
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.
