compliance is mainly limited by the op amp supply voltages.
This circuit can be used in 4 to 20 mA current transmitters with
up to 500
W of load.

R3 in theory can be made small to achieve the current needed
within the U4 output current driving capability. In this circuit,
the AD8510 can deliver
±20 mA in both directions and the
voltage compliance approaches
±15 V.
This circuit is versatile, but users must pay attention to the
compensation. Without C1, it can be shown that the output
impedance becomes:

If the resistors are perfectly matched, ZO is infinite, which is
highly desirable. On the other hand, if they are not matched, ZO
can either be positive or negative. The latter, because of the
pole in the right S-plane, can cause oscillation. As a result, C1
in the range of a few pF is needed to prevent the oscillation. For
critical applications, C1 should be found empirically without
overcompensating.
Boosted Programmable Voltage Source
For users who need higher than 20 mA current driving capabil-
ity, they can add an external op amp and power transistors. The
capacitive loading capability will change, but it can still drive
100 nF capacitive load without oscillation in this circuit. Figure 7
shows a programmable power supply with 200 mA capability.
