Introduces the function and use of the Atmel XMEGA A series ADC, including resolution, sampling rate, conversion time, input selection, result type, etc.
The document is a step‑by‑step training guide for the ADC of the Atmel XMEGA A‑series. It covers single‑ended conversion, the compare function, virtual channels and event‑triggered conversion through four practical tasks.
Additional sections list resources, support contacts and a brief summary of the covered features, with links to the XMEGA manual, Atmel AVR Studio and related tools.
| ADC resolution | 12‑bit |
|---|---|
| Maximum sample rate | 2 MSPS |
| Conversion time (12‑bit) | 7 ADC clock cycles (+1 if gain enabled) |
| Number of virtual channels | up to 4 (2 for D series) |
It provides a 12‑bit resolution.
The ADC can use up to four virtual channels (two on the D series).
It can convert up to 2 million samples per second.
7 ADC clock cycles, plus one extra cycle if the gain stage is enabled.
