5 Volt Precision Reference Standard Upgrade – Part 1

This project will be in two parts. This first part here covers the circuit upgrade to allow the 5 volt Precision Reference standard covered in my previous video to be switched to give 100mV, 1V, 5V and 10V outputs. We will test the upgrade circuit on a breadboard and show how it can be simply calibrated.

Here’s a link to the original project video.
