Note 6-1
• Stresses above the specified parameters could cause permanent damage to the device. This is a stress rating
only. Therefore, functional operation of the device at any condition above those indicated in the operation sec-
tions of this specification are not implied.
• 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. When this possibility exists, it is suggested that a clamp circuit be used.
