Bipolar to Unipolar Converter Example
The calculator solves the summing amplifier resistors based on the input and output voltage range requirements. It is a great tool to design a bipolar to unipolar converter, as an example and other circuits.
Enter the input range, Vin1 to Vin2, the output range, Vout1 to Vout2 and a reference voltage Vref which helps in adjusting the common-mode level of the amplifier. Since the 2-input summing amplifier has 4 resistors, you need to choose two resistors, R1 and R3, and calculate R2 and R4. For more details about this calculator read How to Design a Summing Amplifier Calculator.
Given Input Range
| Vin1 = | V | Vin2 = | V |
Required Output Range
| Vout1 = | V | Vout2 = | V |
Choose a Reference Voltage
| V2 = | V |
Choose R1 and R3
| R1 = | kOhm | R3 = | kOhm |
Calculate R2 and R4
| R2 = | kOhm | R4 = | kOhm |

The default values show a bipolar to unipolar converter with the input range -5V to +5V and output 0 to 3V. If the results are negative or infinity you need to change the input data. Read How to Design a Summing Amplifier Calculator for help.
