*Stresses above those listed may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other condition above those indicated in the
operational sections of this specification is not implied.
NOTE: When powering this device from laboratory or system power supplies, it is important that the
Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit
voltage spikes or "glitches" on their outputs when the AC power is switched on or off. In addition,
voltage transients on the AC power line may appear on the DC output. If this possibility exists it is
suggested that a clamp circuit be used.
