DC-COUPLED DAC OUTPUT
In some cases, it may be desirable to dc-couple the AD973x
output. The best method for doing this is shown in Figure 94.
This circuit can be used with voltage or current feedback
amplifiers. Because the DAC output current is driving a virtual
ground, this circuit may offer enhanced settling times. The
settling time is limited by the op amp rather than by the DAC.
This circuit is intended for use where the amplifiers can be
powered by a bipolar supply.

An alternate circuit is shown in Figure 95. It suffers from dc
offset at the output unless the DAC load resistors are small,
relative to the amplifier gain and feedback resistors.
