This was a very interesting presentation. You and Peter are both giving me some good projects to work on.

Thanks John

That's very cool, low component count and easy to replicate, a great tool for any workshop as you say, for spot checks and the like

The lower accuracy rating is only due to the lower tolerance resistors as the ref200 is rated at 0.5%. If one wanted to build this more accurate, just get more accurate resistors

Very similar content coming for my power supply project for the current source, DC Load and of course the main PSU reference and current sense. As with all things like this, it is down to the ability to measure the signal of interest and the quality of the parts involved

Good post and an interesting chip.

I am continually amazed at the speed at which useful functions are being integrated into these tiny chips.
