capacitor in parallel with a 2.2µF capacitor. Bypass REFP,
REFN, and COM each to GND with a 0.33µF ceramic
capacitor. Bypass REFIN to GND with a 0.1µF capacitor.
Multilayer boards with separated ground and power
planes yield the highest level of signal integrity. Use a
split ground plane arranged to match the physical loca-
tion of the analog ground (GND) and the digital output-
driver ground (OGND) on the device package. Connect
the MAX19713 exposed backside paddle to the GND
plane. Join the two ground planes at a single point so
the noisy digital ground currents do not interfere with
the analog ground plane. The ideal location for this
connection can be determined experimentally at a
point along the gap between the two ground planes.
Make this connection with a low-value, surface-mount
resistor (1Ω to 5Ω), a ferrite bead, or a direct short.
Alternatively, all ground pins could share the same
ground plane, if the ground plane is sufficiently isolated

from any noisy digital system’s ground plane (e.g.,
downstream output buffer or DSP ground plane).
Route high-speed digital signal traces away from sensi-
tive analog traces. Make sure to isolate the analog
input lines to each respective converter to minimize
channel-to-channel crosstalk. Keep all signal lines short
and free of 90° turns.
Integral nonlinearity is the deviation of the values on an
actual transfer function from a straight line. This straight
line can be either a best-straight-line fit or a line drawn
between the end points of the transfer function, once
offset and gain errors have been nullified. The static lin-
earity parameters for the device are measured using
the best-straight-line fit (DAC Figure 14a).
