Hi,

I plan to use S6E2C1AH0AGV2000A and would like to know the impedance and tolerance (xx ohm, +/- xx % or min.) of analog port AN00 to 31 terminal.

I can find the impedance value in datasheet which is 12Kohm "Analog input resistance, Rain" because our AVCC design is 3.4V, but tolerance is not described.

So, could you please let me know the tolerance or minimum value?

Please feel free to tell me if you need more information.

Best regards,

Shohei

Dear Shohei-san,

What you would like as Impedance is RAIN in datasheet, please consider the tolerance would be +0%.

thank you.

Dear Shohei-san,

Could you please let us know the detail of background for this query?

Do you want to calculate the sampling rate?

thank you.

Hi Takashi-san,

Thanks for the reply. I'm trying to calculate the voltage accuracy of dividing resistors.

Therefore I'd like to know the impedance and tolerance between analog pin(s) and GND if possible.

Best regards,

Shohei
