ADC Oversampling Techniques for Stellaris Microcontrollers (AN01239) (Rev. A)

Published Date: 01/08/2013

Description

Some members of the Stellaris microcontroller family have an analog-to-digital converter (ADC) module. The hardware resolution of the ADC is 10 bits; however due to noise and other accuracy diminishing factors the true accuracy is less than 10 bits. This application report provides a software-based oversampling technique resulting in an improved effective number of bits (ENOB) in the conversion
