In my previous article on common op-amp circuits, I mentioned that operational amplifiers were used for analog computing, where analog circuits simulated the behavior of complex systems. That article ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

You could argue that the integrated amplifier is arguably the most critical component in modern hi-fi. It combines a power amplifier, a built-in phono preamplifier (which you need to connect a ...

Bob Pease got an e-mail in 2006 from an engineer who was having trouble with an integrator circuit. Amplifiers are often called op amps because they were originally used as operational amplifiers.

Our favorite integrated amplifiers for audiophiles in 2025 includes models from WiiM, Advance Paris, Moon by Simaudio, Quad and Marantz. Integrated amplifiers have roared back into the audiophile ...

The integrated amplifier market is evolving and that’s a very good thing for audiophiles looking in 2022. 2022 was a really good year for those looking at the network amplifier, receiver, and ...

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 ...
