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 15 and Figure 16 display the output amplifier
characteristics driving a 1000 pF, 0 mA to 10 mA load.

LOAD REGULATION
The AD586 has excellent load regulation characteristics. Figure 17
shows that varying the load several mA changes the output by a
few µV. The AD586 has somewhat better load regulation per-
formance sourcing current than sinking current.
TEMPERATURE PERFORMANCE
The AD586 is designed for precision reference applications
where temperature performance is critical. Extensive tempera-
ture testing ensures that the device maintains a high level of
performance over the operating temperature range.
Some confusion exists with defining and specifying reference
voltage error over temperature. Historically, references have
been characterized using a maximum deviation per degree
Celsius, that is, ppm/°C. However, because of nonlinearities in
temperature characteristics that originated in standard Zener
references (such as “S” type characteristics), most manufacturers
have begun to use a maximum limit error band approach to
specify devices. This technique involves measuring the output at
three or more different temperatures to specify an output volt-
age error band.
