Микроконтроллеры AVR

Но в даташите написано: "The ADC has 12-bit resolution and is capable of converting up to 2 million samples per second". А в апликэйшене "AVR1324: XMEGA ADC Selection Guide" сказано:

• 2MHz maximum ADC frequency • Minimum single result propagation delay of 2.5 μs (8-bit resolution) • Minimum single result propagation delay of 3.5 μs (12-bit resolution)

Или МГц и мегасамплы - не одно и то же?

Pipelined ADC The propagation delay for a single conversion is the same as that for a cyclic ADC. The main difference is that four channels can share the 12 basic elements. The maximum conversion rate is a complete conversion every ADC cycle. F_{ADC max} = 2MHz => Propagation delay = 2Msps Propagation delay for a 12-bit conversion = 1 ADC cycle = 2Msps
