10-bit ADC - Configuration Guide for SPC56xBxx and
SPC56xCxx products
Introduction
The aim of this document is to clarify the usage of the ADC 10-bit SAR peripheral timing
parameters in order to help the user to find the best configuration to optimize the conversion
time and the quality/precision of the sampled signal considering its input impedance.
This document describes an application able to acquire sinusoidal signals of up to 500 kHz
using two DMA channels triggered by PIT and EOC signal.
The quality of the signal is estimated using an offline computation of the FFT of the sampled
values.
