AD588
Each AD588 A and B grade unit is tested at ?25°C, 0°C, +25°C,
+50°C, +70°C, and +85°C. This approach ensures that the
variations of output voltage that occur as the temperature
changes within the specified range is contained within a box
whose diagonal has a slope equal to the maximum specified
drift. The position of the box on the vertical scale changes from
The AD588 has three amplifiers that can be used to implement
Kelvin connections. Amplifier A2 is dedicated to the ground
force-sense function, while uncommitted Amplifier A3 and
Amplifier A4 are free for other force-sense chores.

In some single-output applications, one amplifier can be
unused. In such cases, the unused amplifier should be
connected as a unity-gain follower (force and sense pin tied

The Kelvin connection of Figure 14 overcomes the problem by
including the wire resistance within the forcing loop of the
amplifier and sensing the load voltage. The amplifier corrects
