will create a voltage divider between the dynamic input
impedance of the ADC and the decoupling resistors.
Choosing too small of a resistor will possibly prevent the
resistor from properly damping the load transient caused
by the sampling process, prolonging the time required for

settling. 16-bit applications typically require a minimum
of 11 R-C time constants. It is recommended that the ca-
pacitor chosen have a high quality dielectric (for example,
C0G multilayer ceramic).
