CV fixed gain, variable offset
This started out as an educational schematic to show how to take a Control Voltage that ranges from 2.2V to 10V, and expand it to cover 0V to 10V. The differential amplifier gain is set by R2/R1 and R4/R3, where the resistors should match. The trim resistor allows 0V to be dialed in.
