TURN-ON TIME 10V 1mV 100mS
Upon application of power (cold start), the time required for
VIN
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 when the horizontal scale is expanded to l ms/cm in Figure 10. Output turn-on time is modified when an external noise reduc- 00529-010 tion capacitor is used. When present, this capacitor acts as an additional load to the current source of the internal Zener Figure 11. Turn-On with 1µF CN Characteristics diode, resulting in a somewhat longer turn-on time. In the case of a 1 µF capacitor, the initial turn-on time is approximately

plete references.
VIN
Many ADCs and DACs present transient current loads to the reference, and poor reference response can degrade the per- formance of the converter.

Figure 12, Figure 13, and Figure 14 display the characteristics of the AD586 output amplifier driving a 0 mA to 10 mA load.
