Hi, There are 480,000 different combinations of standard 1% resistor values. If you need 2.75 volts from a 5.00 volt reference, which of those 480,000 pairs will give you the closest result?
For this example there are 9 resistor pairs that will get you to within
0.5%, but one resistor pair will get you within 0.15%. Only 1 out of 480,000 combinations is the best pair!!
The Best Pair II resistor calculator program will calculate and display the twenty one best voltage divider resistor pairs, as well as the error voltages, percent error, "Perfect R2" and "R Thevenin" values. Results can be scaled to any decade of course.
BestPair has been upgraded to Best Pair II. If you are interested you can get it with instant download delivery here -->

Thanks for looking.
