Part Number: REF5040
This customer has failed EMC testing and identified the REF5040 as being the culprit. Once the device is replaced with REF3140, the board passes the test. Can you please provide any insight to possible reasons? This voltage reference is used for an ADC. We are still working to get more details and possibly a schematic. The marking on the device is 55H Z203. Can you tell us the date of manufacture?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
