AD587  
TURN-ON TIME

Upon application of power (cold start), the time required for  
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 7, Figure 8, and Figure 9 show the turn-  
on characteristics of the AD587. These figures show the settling  
to be about 60 μs to 0.01%. Note the absence of any thermal tails  
when the horizontal scale is expanded to 1 ms/cm in Figure 8.

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  
400 ms to 0.01%, as shown in Figure 9.

DYNAMIC PERFORMANCE  
The output buffer amplifier is designed to provide the AD587  
with static and dynamic load regulation that is superior to less  
complete references.

Many ADCs and DACs present transient current loads to the  
reference, and poor reference response can degrade the con-  
verters performance.
