Question about AD8495

Hi All,

I have a question about the AD8495. Please take a look at the attachment.

I think it is not out of spec, but I would like to know the cause of these variation.

Regards,

Kazu

  • Hi Kazu,

    I can give you the polynomial coefficients to calculate the expected output voltage of the AD8495 for different temperatures and give you an estimate of the expected error.  Can you tell me what kind of thermocouple/thermocouples you plan on using?  Also, what is the temperature range that you are trying measure?  From the first picture I can see the low end is about -25C and the high end is around 300C but I'd like to confirm.  Is your reference temperature going to be 32C?
