MAX10 A/D sampling rate

In MAX10 Analog to Digital Converter User Guide on page 17 the folowing is denoted:

The maximum cumulative sampling rate in normal sampling mode is 1 MSPS.

 

So if I use 9 A/D inputs in normal mode at maximum rate, each analog input will be sampled at 1M /9 rate?

If I'm using the temperature sensing mode + 8 analog inputs, still each input will be measured at 1M/9 rate ( except the tempertaure)? or each analog input will be measured at 50khz rate?

Hi Zvi,

 

Please find my response below:

[1] So if I use 9 A/D inputs in normal mode at maximum rate, each analog input will be sampled at 1M /9 rate?

A: Yes as MAX10 uses SAR ADC.

 

[2] If I'm using the temperature sensing mode + 8 analog inputs, still each input will be measured at 1M/9 rate ( except the tempertaure)? or each analog input will be measured at 50khz rate?

A: It is 1Msample /8 because you have 8 normal analog input pin (which Cumulative samples) in normal mode and ADC switchover for TSD measurement at 50 KHz.

 

Thank You
