AD8610/AD8620
The AD8610/AD8620 maintain this fast settling time when
loaded with large capacitive loads, as shown in Figure 62.
Output Current Capability
The AD8610/AD8620 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 supplies of ±13 V. Figure 64 and Figure 65
compare the output voltage vs. load current of AD8610/
AD8620 and OPA627.

Although operating conditions imposed on the AD8610/AD8620
(±13 V) are less favorable than the OPA627 (±15 V), it can be
seen that the AD8610/AD8620 have much better drive capability
(lower headroom to the supply) for a given load current.
Operating with Supplies Greater than ±13 V
The AD8610/AD8620 maximum operating voltage is specified
at ±13 V. When ±13 V is not readily available, an inexpensive
LDO can provide ±12 V from a nominal ±15 V supply.
