star-point (Figure 11) connecting the two ground sys-
tems (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 com-
parator. Bypass VDD to the star ground with a network
of two parallel capacitors, 0.1F and 1F, located as
close as possible to the power supply pin of the
MAX157/MAX159. Minimize capacitor lead length for
best supply-noise rejection and add an attenuation
resistor (10
) if the power supply is extremely noisy.
