C. However, because of nonlinearities in
temperature characteristics which originated in standard Zener
references (such as “S” type characteristics), most manufactur-
ers have begun to use a maximum limit error band approach to
specify devices. T his technique involves the measurement of the
output at three or more different temperatures to specify an out-
put voltage error band.
Figure 9 shows the typical output voltage drift for the AD586L
and illustrates the test methodology. T he box in Figure 9 is
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.
T he slope of the diagonal drawn from the lower left to the upper
right corner of the box determines the performance grade of the
device.

C. T his approach ensures that the variations
of output voltage that occur as the temperature changes within
the specified range will be contained within a box whose diago-
nal has a slope equal to the maximum specified drift. T he posi-
tion of the box on the vertical scale will change from device to
device as initial error and the shape of the curve vary. T he maxi-
mum height of the box for the appropriate temperature range
and device grade is shown in Figure 10. Duplication of these
results requires a combination of high accuracy and stable tem-
perature control in a test system. Evaluation of the AD586 will
produce a curve similar to that in Figure 9, but output readings
may vary depending on the test methods and equipment utilized.

Figure 10. Maximum Output Change in mV
In some applications, a varying load may be both resistive and
capacitive in nature, or the load may be connected to the
AD586 by a long capacitive cable.
Figure 7 displays the output amplifier characteristics driving a
1000 pF, 0 to 10 mA load.

T he AD586 has excellent load regulation characteristics. Figure
8 shows that varying the load several mA changes the output by
a few
μ
V. T he AD586 has somewhat better load regulation per-
formance sourcing current than sinking current.

T he AD586 is designed for precision reference applications
where temperature performance is critical. Extensive tempera-
ture testing ensures that the device’s high level of performance is
maintained over the operating temperature range.
Some confusion exists in the area of defining and specifying ref-
erence voltage error over temperature. Historically, references
have been characterized using a maximum deviation per degree
