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 ...

You just finished looking at the data sheet specifications for an op amp that looks like a good fit for your design. You want to run simulations on your design before you head into the lab to build up ...

Battery-powered op-amp applications, such as those found in automotive and marine equipment, have only a single available power source. Other applications, such as computers, may operate from the ac ...

If you’re designing a linear circuit of any kind today, it most likely involves an op amp and even an analog-to-digital converter (ADC). The op amp is your go-to device simply because it can be ...

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 ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

Most PC “mic” inputs are pretty average for noise and distortion, and they’re usually mono. Plus, they can’t properly take balanced, pro microphones that often need 48-V phantom power. This ...
