The gain equation for the op amp is = (+). However, in this circuit V − is a function of V out because of the negative feedback through the R 1 R 2 network. R 1 and R 2 form a voltage divider, and as V − is a high-impedance input, it does not load it appreciably. Consequently Ver mais An 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. In this configuration, an op amp produces an output potential … Ver mais Ideal op amps An ideal op amp is usually considered to have the following characteristics: • Infinite open-loop gain G = vout / vin • Infinite Ver mais Op amps may be classified by their construction: • discrete, built from individual transistors or tubes/valves Ver mais Use in electronics system design The use of op amps as circuit blocks is much easier and clearer than specifying all their individual circuit elements (transistors, resistors, etc.), whether the amplifiers used are integrated or discrete circuits.
