Programmable Gain Amplifier Circuit Diagram

Programmable Gain Amplifier Circuit Diagram . The circuit uses the DG212 which controlling the gain using resistors. To calculate the different gains SW4 should be closed. Gain error is determined only by the resistor tolerance op amp offset and CMR will limit accuracy of circuit .
