AD587
DEVICE
Each AD587J and AD587K grade unit is tested at 0°C, 25°C,
and 70°C. Each AD587U grade unit is tested at ?55°C, +25°C,
and +125°C. This approach ensures that the variations of the
output voltage that occur as the temperature changes within the
specified range are 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 device to device as initial
error and the shape of the curve vary. The maximum height of
the box for the appropriate temperature range and device grade
is shown in Figure 16. Duplication of these results requires a
combination of high accuracy and stable temperature control in
a test system.

NEGATIVE REFERENCE VOLTAGE FROM AN AD587
The AD587 can be used as shown in Figure 17 to provide a
precision ?10.000 V output. The +V IN pin is tied to at least a
+3.5 V supply, the output pin is grounded, and the AD587
ground pin is connected through a resistor (R S ) to a ?15 V
supply. The ?10 V output is taken from the ground pin (Pin 4)
instead of V OUT . It is essential to arrange the output load and the
supply resistor (R S ) so that the net current through the AD587 is
between 2.5 mA and 10.0 mA (R S should be kept below 1 kΩ).
The temperature characteristics and long-term stability of the
device is essentially the same as that of a unit used in the
standard 10 V output configuration.
