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 ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

One of the biggest problems for designers of op-amp circuitry arises when the circuit must be operated from a single supply, rather than ± 15 V. This application note provides working circuit examples ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...
