current into the die substrate, which is resistive. Load dis-
charge currents will cause "ground bounce" noise in the sub-
strate that will degrade noise performance if that current is
large enough. The larger the output capacitance, the more
current flows through the die substrate and the greater is the
noise coupled into the analog channel, degrading noise per-
formance.

To keep noise out of the power supply, keep the output load
capacitance as small as practical. It is good practice to use a
100 Ω series resistor at the ADC output, located as close to
the ADC output pin as practical. This will limit the charge and
discharge current of the output capacitance and maintain
noise performance.
