Note 3: Slew rate is measured in a gain of –2. For
±15V supplies measure
between
±10V on the output with ±6V on the input. For ±5V supplies
measure between
±2V on the output with ±1.75V on the input.
Note 4: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2
πVP.
The q denotes the specifications which apply over the full operating
temperature range.
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 and is
exclusive of warm-up drift.
