3.1.2.4 12-bit ADCC with +/- Ch. Sel.

12-bit ADC with Computation and Positive and Negative Channel Selection

3.1.2.4.1 Introduction

This Analog-to-Digital Converter with Computation (ADCC) module converts both single-ended and differential analog input signals to a 12-bit binary representation of that signal. This peripheral takes in analog signals and combines them into a Sample-and-Hold (S/H) circuit. It is then fed to a converter to turn this measurement into a 12-digit binary number and is stored in the ADC result registers. This ADCC module also features positive and negative channel grouping which allows multiple input channels to be grouped together into a single input channel.
