Description
Operation amplifier and voltage divider are the basic circuits for hobbyist or electronic engineers. This app is used to calculate all possible resistor values approximate a desired ratio
Features:
1. Calculate resistor values of voltage divider
2. Calculate resistor values of inverting amplifier gain
3. Save component values in CSV file (Excel file)
4. Use preferred values of resistors
Features in PRO version only:
1. No Ad
2. Can use preferred value 1% and 5% for resistor
3. No limitation
Note :
1. For those who need support please email to the designated email.
Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.
