At the moment I am looking at the spec's of the AD7872 ADC.

I need to verify and measure some spec for our customer.


One of those spec is the INL.

Can you tell me how it is measured.

- Is the reference line between the endpoints( code 0x0000 - code 0x3FFF)

  or between midscale (code 0x1FFF and endpoints(code 0x0000 and code 0x3FFF) to cerrect for for the offest error.

- Is the INL the result of the Endpoint or Bestfit line.

- Have you got a graph of the INL


Thanks in advance for handeling this question
