  Part Number: REF5025 A number of our boards with REF5025AIDGKR , measures the VREF with error greatere then the 2.5mV I expect from the REF5025. I'm getting as much as 20mv above 2.500 V LOT CODE TI83 is there a bad lot code ?

  Part Number: REF5025 I would like to know if the REF5025 noise plot in Figure 13 is the 0.1hz to 10hz noise. The spec is 3uVpp (typ.) so I suspect it might not be. Please explain what is the noise bandwidth for this test case. Thanks.
