the output voltage to reach its final value within a specified
error band is defined as the turn-on settling time. Two compo-
nents normally associated with this are the time for the active
circuits to settle, and the time for the thermal gradients on the
chip to stabilize. Figure 9, Figure 10, and Figure 11 show the
turn-on characteristics of the AD586. It shows the settling to be
about 60 μs to 0.01%. Note the absence of any thermal tails
Output turn-on time is modified when an external noise reduc-
tion capacitor is used. When present, this capacitor acts as an
additional load to the current source of the internal Zener
diode, resulting in a somewhat longer turn-on time. In the case
of a 1 μF capacitor, the initial turn-on time is approximately
