These common op-amp circuits are useful for amplifying various analog signals. The ideal op amp model helps us understand how these circuits operate. For more detailed information on op amp circuits, ...

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 res… ...

The circuit, shown at left, works with any rail-to-rail op amp; but it works best if the quiescent current is very small compared with the largest current the op amp can sink and if there is a good ...

Op amps are pretty dang cool, with a lot of neat circuits you could build using them. I actually just put the finishing touches on my first actual op amp design and sent the design files over to ...

The op-amp is a differential amplifier, sensitive to the difference in potential between the + and – inputs. A comparator IC (e.g; LM.339) is really just a specialized op-amp that has been ...

Basic Op-Amp Circuits. Comparator circuit. A comparator circuit (Fig. 1) compares two input voltages and outputs a binary signal indicating which is larger.

By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the value of R2 as this resistor sets up a voltage divider with the very small input ...

Consider a differential op-amp circuit that has a positive input with gain of +5 and a negative input with gain of –5 (Fig. 1). R F was selected to be 100 kΩ.

The history of overdrives really starts with the op-amp, a component designed to create distortion-free amplification. Circuit designers took these chips and started to make stompboxes that used this ...
