Layout, Grounding, and Bypassing
For best performance, use PC boards. Wire-wrap config-
urations are not recommended since the layout should
ensure proper separation of analog and digital traces. Do
not run analog and digital lines parallel to each other, and
do not lay out digital signal paths underneath the ADC
package. Use separate analog and digital PCB ground
sections with only one star point (Figure 14) connecting
the two ground systems (analog and digital). For lowest
noise operation, ensure the ground return to the star
ground’s power supply is low impedance and as short as
possible. Route digital signals far away from sensitive
analog and reference inputs.
High-frequency noise in the power supply (VDD) could
influence the proper operation of the ADC’s fast
comparator. Bypass VDD to the star ground with a
0.1F capacitor located as close as possible to the
MAX11600–MAX11605 power-supply pin. Minimize
capacitor lead length for best supply-noise rejection,
and add an attenuation resistor (5
) if the power sup-
ply is extremely noisy.
