DC PARAMETERS

6.1

Maximum Ratings

Note 1: Stresses above the specified parameters could cause permanent damage to the device. This is a stress rat-

ing only. Therefore, functional operation of the device at any condition above those indicated in the operation

sections of this specification are not implied.

2: When powering this device from laboratory or system power supplies, it is important that the absolute max-

imum 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.
