bounded on the sides by the operating temperature extremes
and on the top and the bottom by the maximum and minimum
output voltages measured over the operating temperature
range. The slope of the diagonal drawn from the lower left to
the upper right corner of the box determines the performance
grade of the device.

NEGATIVE REFERENCE VOLTAGE FROM AN AD586
The AD586 can be used to provide a precision ?5.000 V output,
as shown in Figure 19. The V IN pin is tied to at least a 6 V supply,
the output pin is grounded, and the AD586 ground pin is con-
nected through a resistor, R S , to a ?15 V supply. The ?5 V output
is now 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 AD586 is between 2.5 mA

unit used in the standard +5 V output configuration.

box whose diagonal has a slope equal to the maximum specified
drift. The position of the box on the vertical scale will change
from device to device as initial error and the shape of the curve
vary. The maximum height of the box for the appropriate tem-
perature range and device grade is shown in Table 5. Dupli-
cation of these results requires a combination of high accuracy
and stable temperature control in a test system. Evaluation of
the AD586 will produce a curve similar to that in Figure 18, but
output readings could vary depending on the test methods and
equipment used.

USING THE AD586 WITH CONVERTERS
The AD586 is an ideal reference for a wide variety of 8-, 12-, 14-,
and 16-bit ADCs and DACs. Several representative examples are
explained in the following sections.
