Wideband op amp circuit
The circuit shown in Figure has overload protection measures. When the circuit has DC-coupled input, the input terminal can be connected to RC blocking network. When the switch S is opened, voltage amplification factor Ku = 1 ( voltage follower ). When S is closed, Ku = 10. For example, R1 = 100kΩ, R2 = R1 / ( Ku- 1 ) = 100/ 9 = 11.1kΩ. R2 = 10kΩ, the circuit is connected to a 2.5kΩ potentiometer Rp in series. The circuit shown as Figure b uses 10 ~ 20V voltage source, this input terminal is connected to a voltage divider.
