(“star” ground point) at GND. Connect all other analog
grounds to this ground. No other digital system ground
should be connected to this single-point analog
ground. The ground return to the power supply for this
ground should be low impedance and as short as pos-
sible for noise-free operation.
High-frequency noise in the power supplies can affect
the ADC’s high-speed comparator. Bypass these sup-
plies to the single-point analog ground with 0.1F and
4.7F

the
MAX1202/MAX1203. Minimize capacitor lead lengths
for best supply-noise rejection. If the +5V power supply
is very noisy, a 10
resistor can be connected as a
lowpass filter, as shown in Figure 18.
