Didn't Bob Pease say something like "The front page of the datasheet giveth, and the spec pages taketh away"? A designer definitely needs to look at the whole datasheet to understand what the part can do and what it will cost. Thanks for the video!

The 5 volt reference spec sheet rates the precision as +-0.2% not +-0.2V so it would be 5V +-0.01V or almost the same accuracy as a the Ref 102A which would be +-0.1% if we were comparing on a similar basis.

Thank you.

Nice video! 👍 Future exploring required!

Great video! Love your channel! Video suggestion: Make a video reviewing your lab equipment. Just a suggestion, definitely enjoy your channel content. 👍🏻

I have a hand full of old voltage reference chips and the REF02s and 03s didn't measure to well but I have one MC1403U which is within a millivolt to 2.500v even though the data sheet is nothing great. Because its accuracy is so good, Its is my quick check for my DVMs.

Request for future video: might could you do one on jfets, and how to select for characteristics?

Specifications must remain valid over all parts, temperatures, and time. Manufacturers can make no money if their customers return too many parts. Thus, their specifications are quite conservative. Assuming a normal distribution, about 95% of them are "typical" and fewer than one in 100k or so fail specs. If the environment is controlled, we can expect performance significantly better than specified.

What are those yellow components you use in parallel on the voltage rails of the breadboard?

Are the a/b/c chips manufactured the same and then just graded at the factory during testing?
