*Stresses above the specified parameters 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. When this possibility
exists, it is suggested that a clamp circuit be used.
