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 in a gain of –2 between ±10V on the output
with ±6V on the input for ±15V supplies and ±2V on the output with
±1.75V on the input for ±5V supplies.
Note 4: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πVp.
