Simple Gain-Controlled Op Amp Circuit Diagram

This is a Simple Gain-Controlled Op Amp Circuit Diagram. In this circuit the gain controller uses a 4066 quad bilateral switch to electronically select a feedback resistor for the 741 op amp. One or more switches can be turned on at the same time to produce a stepped, variable-gain range from less than 1 to 100.
