DC ELECTRICAL CHARACTERISTICS

Note:

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.
