voltage-divider-calculator | selecting voltage divider components given constraints

voltage-divider-calculator is a C++ library. voltage-divider-calculator has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This is a simple console utility for solving a problem every electrical engineer faces frequently: choosing parts for a voltage divider. Very often you are limited by parts you have on the shelf (so you can prototype right now without waiting for an order to arrive), or have constraints imposed on component values. This tool takes a series of command line arguments specifying the desired division ratio, a text file listing the available resistor values available in inventory, and outputs suggested component values and error bounds. Additional optional arguments allow you to specify constraints: for example, total resistance of the divider must be at least X but no more than Y, or the lower resistor (R2) must have a fixed value.
