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 Jordyn,

    First, what cause the +/-1.5mV error? Is it quantization noise?

    Second, my understanding about the total error from the AD8495 under the temperature range of  0 to 220 degC

    is +/-0.5 degC (CN-0354 with nonlinearity correction, CN-0354 Figure 3.) and +/-1.5mV you calculated in the last mail. Am I correct?

    Last, as I asked you before, I need the AD8495 curve  with nonlinearity correction under the temperature range of -25degC to 0degC. Could you send it to me?

    Regards,
