Doing ADC measurements properly

An analogue-to-digital converter (ADC) cannot ensure ideal accuracy by itself. A number of parameters can affect the achievable accuracy of an ADC in an application. To achieve optimal performance, it is necessary to consider the application note provides comprehensive guidelines on the procedure.

This document gives comprehensive guidelines on how to correctly select and design the required external RC components for a SAR ADC input based upon a selected acquisition time and other converter parameters that can be found in the controller documentation.
