DYNAMIC PERFORMANCE
The output buffer amplifier is designed to provide the AD587
with static and dynamic load regulation superior to less com-
plete references.
Many A/D and D/A converters present transient current loads
to the reference, and poor reference response can degrade the
converter’s performance.
Figure 6 displays the characteristics of the AD587 output ampli-
fier driving a 0 mA to 10 mA load.
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 internal Zener diode’s current source, re-
sulting in a somewhat longer turn-on time. In the case of a 1
μ
F
capacitor, the initial turn-on time is approximately 400 ms to
0.01% (see Figure 5c).
