Analog features are important for all applications that need to interface with the outside world. The XMEGA features high-end analog modules for improved analog performance and reduced need for external components. Its ADC is 12-bit and offers an extremely fast sample rate of up to 2 mega samples per second (MSps). Also, some XMEGA devices have a dual ADC to further improve sample rate and allow for synchronous sampling of two external analog signals. The high sample rate and DMA support on the ADC allows for easy oversampling to further increase the resolution of the analog measurement. The ADC also incorporates differential input with a programmable gain stage of up to 64x gain. This can save the cost of using external amplifiers and increase the dynamic range of the ADC without any additional cost. Accurate internal voltage references are also available, which reduces the need for using external reference voltages. The integrated Digital-to-Analog converters (DACs) are also 12-bit, with up to a 1 MSps conversion rate. They provide accurate voltage output without the need for external filters. There are also between two and four DAC outputs  available on each XMEGA device. All I/O pins on XMEGA can sink and source more than 10 mA allowing high current input and output which reduces the need for external transistors to drive LEDs, power transistors, and other high current components. This is combined with high ESD and EMC performance to make XMEGA an excellent fit for industrial applications in harsh environments because of the reduced need for adding external protection. Additionally, the accurate internal RC oscillators have low drift over temperature and voltage which means they can be used for applications requiring a down to +/- 1% accurate clock source, removing the cost of external clock source. Combined, XMEGA offers leading analog integration and a feature set that is not available in other general purpose MCUs.
