About Operational amplifier tools
An operational amplifier (often op-amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input. It is the basic building block in analog circuits.
This app is a collection of operational amplifier calculators including inverting amplifier, non-inverting amplifier, comparators, filters, oscillators etc. It is suitable for hobbyist, electronic engineers or professionals.

* Non-inverting amplifier
* Differential amplifier
* Summing amplifier
* Inverting comparator
* First order filter
* 2nd-order filter (HPF)
* Phase-shift oscillator
* Colpitts oscillator
* Limit 5 combinations of component values
* Support English, German, French, Italian, Spanish, Portuguese, Japanese, Korean, Traditional Chinese, Simplified Chinese, Russian, Hindi, Indonesian, Malay, Thai, Turkish, Vietnamese
PRO features
