Settling Time
The AD8610 has a very fast settling time, even to a very tight error
band, as can be seen from Figure 20. The AD8610 is configured
in an inverting gain of +1 with 2 kΩ input and feedback resistors.
The output is monitored with a 10 ×, 10 M, 11.2 pF scope probe.

Output Current Capability
The AD8610 can drive very heavy loads due to its high output
current. It is capable of sourcing or sinking 45 mA at ±10 V output.
The short circuit current is quite high and the part is capable of
sinking about 95 mA and sourcing over 60 mA while operating with
