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 […]
Design & Build 5 Volt Reference Standard
This project is for the hobbyist to design and build a 5 volt precision voltage reference standard that requires no adjustment but still has an accuracy of ±0.01% or better and a temperature coefficient of ±3 ppm/ºC. Also incorporating an auto switch-off and battery monitor feature. PARTS LIST: 1 x Intersil ISL21009BFB850Z, Precision 5V Voltage […]
