*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.
