This is a very simple OpAmp Circuit Designer for mapping an input voltage to an output voltage by amplification or attenuation with an offset if needed.
All the information in this page is based on my understanding of the analysis and the design given in the book Op Amps for Everyone by Bruce Carter and Ron Mancini.
Neither I nor this page has any official or inofficial relationship with the book or with its authors. I highly recommend you study the book for more information.
Please provide the input and the output voltage range. The calculation is made on the fly (no submit button).
If Vin low is different from Vout low, you also have to use a reference voltage (Vref).
| Vin (V) | Vout (V) | |
| High: | ||
| Low: |
| Vref (V): |
y ≅ () x + ()
| R | calculated | E96 value |
| R1 | ||
| R2 | ||
| Rf | ||
| Rg |
With E96 resistors:
Vout high = V
Vout low = V
