* Stresses above those listed above could cause permanent damage to the device. This is a stress rating only and

functional operation of the device at any other condition above those indicated in the operation 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 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.
