Layout, Grounding, and Bypassing
For best performance, use printed circuit boards. Wire-
wrap boards are not recommended. Board layout
should ensure that digital and analog signal lines are
separated from each other. Do not run analog and digi-
tal (especially clock) lines parallel to one another or run
digital lines underneath the ADC package.
Figure 10 shows the recommended system-ground
connections. A single-point analog ground (star-ground
point) should be established at the A/D ground.
Connect all analog grounds to the star ground. No digi-
tal-system ground should be connected to this point.
The ground return to the power supply for the star
ground should be low impedance and as short as pos-
sible for noise-free operation.
High-frequency noise in the VDD power supply may
affect the comparator in the ADC. Bypass the supply to
the star ground with 0.1F and 1F capacitors close to
the VDD pin of the MAX1106/MAX1107. Minimize
capacitor lead lengths for best supply-noise rejection. If
the power supply is very noisy, a 10
resistor can be
connected to form a lowpass filter.
