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 op amp — short for operational amplifier — is a packaged differential amplifier. The ideal op amp — which we can’t get — has infinite gain and infinite input impedance.

If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits. To promote ...

Op-amps were an invaluable basic technology in 1969. What today’s op-amps can accomplish has expanded dramatically. At present an op-amp is defined as a general-purpose, DC-coupled, high-gain, ...

Creator, AstroSam, built a functional prototype of a brain-computer interface (BCI), called Mind Link. It reads brain signals ...

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 ...

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

Operational amplifiers can be utilized in a wide range of applications. By adding more resistors or capacitors to the circuit, they can be applied to create many different computational circuits.

Some op amps incorporate a voltage-current limiter circuit to protect the amplifier from SOA damage such as a short to ground.
