voltagestandard.com had its origins in 2007 with the publication of our Nuts and Volts magazine article, "Build a .01% Accurate Voltage Reference" http://nutsvolts.texterity.com/nutsvolts/200709/?folio=52. Since that time we have added products and now manufacture reference assemblies that utilize voltage reference IC's from Texas Instruments (REF5050ID) and Linear Technology (LT1021BCN8)
