Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

The circuit shown in Figure 5 is quite versatile. Removing the capacitors causes the circuit to degenerate to the inverting amplifier configuration (see Common op-amp circuits). Leaving the feedback ...

Some typical examples of common-mode signals in op amp circuits are DC bias voltages and coupled noise from electromagnetic fields or parasitic circuit paths. You want an op amp to reject these common ...

The Analog Engineer’s Circuit Cookbook: Op Amps is an example. It compiles more than 25 popular op-amp circuit designs like current sensing, attenuating, and full-wave rectifying into a single e ...

The operational amplifier (op-amp) is a high performance gain device with essentially linear qualities.

The Classics One of the absolute classic op-amp applications is simple signal level scaling, and [David]’s ultra-low-cost pH amplifier circuit for 3.3V MCUs is a great example.
