3.3 ADC

The AVR XMEGA AU MCUs are highly integrated with dual-sixteen channel pipeline ADC modules for high analog accuracy. The high-performance 12-bit pipeline ADC is capable of conversion rates up to 2 million samples per second (MSPS).

The ADC conversion block has a 12-stage pipelined architecture. All the channels of an ADC module use the same ADC pipeline for the conversions, and the pipeline enables a new conversion to be started for each ADC clock cycle. Thus, multiple ADC measurements from different channels can be converted simultaneously and independently.

A wide range of multiplexer (MUX) settings, integrated gain stage, and four virtual input channels make this a flexible ADC module suitable for a wide range of applications such as data acquisition, embedded control, and general signal processing.
