imxrt ADC sampling rate per cahnnel

[lukasz_iwaszkie]

Hey everyone

   The i.MX RT1010 Processor Reference Manual states that ADC has:

• Up to 1MS/s sampling rate
• Up to 16 single-ended external analog inputs

Is the 1MSps stated per channel (thus making 16 * 1Msps sampling possible) or is it available for the ADC as a whole (so sampling all 16 inputs at once would give me ~62 ksps)?

Figure 53-2. ADC block diagram on page 1924 shows only one analog comparator with multiple inputs connected to it so I believe the latter is true?

Hi @lukasz_iwaszkie,

The maximum sampling rate of 1MS/s is true for the whole ADC module, not for each channel individually.
