Figure 10. Turn-On Settling Time
Attempts to drive a large capacitive load (in excess of 1000 pF)
can result in ringing. This is due to the additional poles formed
by the load capacitance and the output impedance of the reference.
A recommended method for driving capacitive loads of this
magnitude is shown in Figure 11.

Figure 11. Turn-On, Settling, and Transient Test Circuit
TRANSIENT RESPONSE
Many ADCs and DACs present transient current loads to the
reference. Poor reference response can degrade the converter’s
performance. Figure 12 displays both the coarse and fine
settling characteristics of the device to load transient of ±50 μA.
It shows the settling characteristics of the device for an
increased reverse current of 50 μA and the response when the
reverse current is decreased by 50 μA. The transients settle to
1 mV in about 3 μs.

Figure 12. Transient Settling Time
A resistor isolates the capacitive load from the output stage,
while the capacitor provides a single-pole, low-pass filter and
lowers the output noise.
