Using an AC Reference
The MAX5174/MAX5176 accept references with AC
components, as long as the reference voltage remains
between 0 and VDD - 1.4V. Figure 11 shows a tech-
nique for applying a sine-wave signal to the reference
input where the AC signal is offset before being applied
to REF. The reference voltage must remain above
AGND.
Power-Supply and Layout Considerations
Wire-wrap boards are not recommended. For optimum
system performance, use printed circuit boards with
separate analog and digital ground planes. Connect
the two ground planes together at the low-impedance
power-supply source. Connect DGND and AGND pins
together at the IC. The best ground connection is
achieved by connecting the DAC’s DGND and AGND
pins together and connecting that point to the system
analog ground plane. This is useful because if the
DAC’s DGND is connected to the system digital
ground, digital noise may infiltrate the DAC’s analog
portion.
Bypass the power supply with a 4.7F capacitor in par-
allel with a 0.1F capacitor to AGND. Minimize capaci-
tor lead lengths to reduce inductance. If noise
becomes an issue, use shielding and/or ferrite beads to
increase isolation.
To maintain INL and DNL performance as well as gain
drift, it is extremely important to provide the lowest pos-
sible reference output impedance at the DAC reference
input pin. INL degrades if the series resistance on REF
pin exceeds 0.1
. The same consideration must be
made for the AGND pin.
