Considerations
As in any precision circuit, careful consideration has to be
given to layout of the supply and ground. The return path
from the GND to the supply ground should be short with
low impedance. Using a ground plane would be ideal. The
supply should have some bypassing on it. A 10
μ
F
tantalum capacitor in parallel with a 0.1
μ
F ceramic with a
low ESR can be used. Ideally these would be placed as
close as possible to the device. Avoid crossing digital and
analog signals, specially the reference, or running them
close to each other.
Output Swing Limitations
The ideal rail-to-rail DAC would swing from GND to V
DD
however, offset and gain error limit this ability. Figure 5
illustrates how a negative offset error will affect the output.
The output will limit close to ground since this is single
supply part, resulting in a dead-band area. As a larger

input is loaded into the DAC the output will eventually rise
above ground. This is why the linearity is specified for a
starting code greater than zero.
Figure 6 illustrates how a gain error or positive offset error
will affect the output when it is close to V
DD
. A positive gain
error or positive offset will cause the output to be limited to
the positive supply voltage resulting in a dead-band of
codes close to full-scale.
