VOUT= -(V1/R1+V2/R2)*RO
This circuit is used to add several signals to one. By setting all resistors to the same value, R1=R2=RO, you get the following formula:
VOUT= -(V1+V2)
You can theoretically add how many signals you like. Here's an example with three in-signals:
VOUT= -(V1/R1+V2/R2+V3/R3)*RO
