Consequently, the slew rate and settling time of a voltage-
switching DAC circuit is determined largely by the output op
amp. To obtain minimum settling time in this configuration,
minimize capacitance at the VREF node (the voltage output node
in this application) of the DAC. This is done by using low input
capacitance buffer amplifiers and careful board design.

Most single-supply circuits include ground as part of the analog
signal range, which in turn requires an amplifier that can
handle rail-to-rail signals. Analog Devices offers a wide range of
single-supply amplifiers, as listed in Table 8 and Table 9.
