ADC14155QML-SP: Under/Over Range Output Codes

Hi Rich,

You are correct. For more info on this, see Table 2 in Section 7.3.

Hi Chase,

Thank you.  I had looked at Table 2 which has the encodings for both offset binary and 2's complement formats ranging from "Negative Full-Scale" to "Positive Full-Scale for particular analog voltage inputs.

However, Table 2 does not address exceptional conditions (e.g., out of range).

Section 6.5 does explicitly address the exceptional conditions for "under range" and "over range" output codes but assumes "Offset Binary Format" (conditions for parameters in Section 6).

So I'm being a bit cautious and want to check that I understand precisely what the output of the ADC will be in 2's complement format under exceptional conditions.

I also looked at the 5962- specification which did not have the out of range encodings for 2's complement format.

So I'd like to make sure I know exactly what the ADC will do before testing in the lab.

Again, thanks, 

rich
