Chapter 9 DC Parameters

9.1

Maximum Guaranteed Ratings

Note 9.1

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 condition above

those indicated in the operation sections of this specification is not implied.

Note 9.2

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.
