Description

If you can't buy the parts, why do the calculation? Standard Values uses EIA standard resistance values in five tolerances to find the optimum solutions for Ohm’s Law problems (including power), voltage dividers, inverting op-amp gain, noninverting op-amp gain, as well as checking entered values against the EIA standard values.

All calculations are optimized to find the best value pair taking the tedium out of doing multiple calculations to find the best result. Doing the calculation manually (picking one value and solving for the other) only results in the best solution by chance.

Standard Values solves for which ever values are missing. For instance, in the voltage divider solver, entering voltages solves for resistance values while entering resistance values solves for the output voltage. When there is not enough information entered help is provided. If desired a nonstandard value can be entered and the entry will be honored.

Most useful EE app available

An EE for > 22 yrs. I have been using this app in its earlier form for the past several years to find standard resistor values for voltage dividers and opamp gain resistors. It has saved me (and will save you) hours of calculating and then finding a standard resistor value to meet the results of your calculations-the app performs this in a single step. The new updated version of this app will also calculate the error associated with the standard resistor tolerance that you will have to choose from which will save you even more time + it now includes an awesome Ohm's law calculator tool.

Standard Values

This is a handy app that helps circuit designers automate a drudge task that they do often. I like the way it's set up and it's clear and easily understood. I didn't need to read the help but I checked it out anyway and it's very clear! Worth the money!

Crashes Every Time

Bought this for a quick reference to standard resistor values. It worked fine on older IOS versions. Now crashes every time I open it. Hasn't been updated since 2009.
Orphan Ware. Sad. Deleted.
