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,
