Application Note

Preliminary

1 Introduction

The Atmel^®AVR^®XMEGA^®ADC module is a high-performance Analog-to-Digital

converter capable of conversion rates up to 2 million samples per second (Msps)

with a resolution of 12 bits. A wide range of multiplexer (MUX) settings, integrated

gain stage and four virtual input channels make this a flexible module suitable for a

wide range of applications, such as data acquisition, embedded control and

general signal processing.

This application note describes the basic functionality of the XMEGA ADC with

code examples to get up and running quickly. The examples are implemented in

software framework (ASF 2.0), which are available for the Atmel AVR XMEGA and

Atmel^®AVR^®UC3^TMmicrocontroller series.

Advanced usage, such as Direct Memory Access (DMA) and the XMEGA Event

System, is outside the scope of this application note. Please refer to the device

datasheets and other relevant application notes such as AVR1304: Using the

XMEGA DMA Controller, and AVR1001: Getting Started with the XMEGA Event

System.
