Shield fast switching signals, such as clocks, with digi-
tal ground to avoid radiating noise to other sections of
the board. Avoid running clock signals near the analog
inputs. Avoid crossover of digital and analog signals.
Traces on opposite sides of the board should run at
right angles to each other. This will reduce the effects
of feedthrough on the board. A microstrip technique is
best but is not always possible with double-sided
boards. In this technique, the component side of the
board is dedicated to ground planes while signals are
placed on the solder side.

Good decoupling is important when using high-resolu-
tion ADCs. Decouple all analog supplies with 10µF tan-
talum capacitors in parallel with 0.1µF HF ceramic
capacitors to AGND. Place these components as close
to the device as possible to achieve the best decou-
pling.
See the MAX1403 evaluation kit manual for the recom-
mended layout. The evaluation board package includes
a fully assembled and tested evaluation board.
