Operational Amplifier

An operational amplifier (op-amp) is a DC–coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals Operational amplifiers had their origins in analog computers, where they were used to do mathematical operations… Read More Operational Amplifier
