The op amp is one type of differential amplifier. Op amps may be packaged as components or used as elements of more complex integrated circuits. Many standard IC op amps cost only a few cents however, some integrated or hybrid operational amplifiers with special performance specifications may cost over US$100 in small quantities. Op amps are used widely in electronic devices today, including a vast array of consumer, industrial, and scientific devices. are determined by external components and have little dependence on temperature coefficients or engineering tolerance in the op amp itself. By using negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc. The popularity of the op amp as a building block in analog circuits is due to its versatility. Operational amplifiers had their origins in analog computers, where they were used to perform mathematical operations in linear, non-linear, and frequency-dependent circuits. In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically 100,000 times larger than the potential difference between its input terminals. Pins are labeled as listed above.Īn operational amplifier (often op amp or opamp) is a DC-coupled high- gain electronic voltage amplifier with a differential input and, usually, a single-ended output.
