They provide relatively high amplification with relatively low noise or distortion, are pretty darn cheap, flexible in their setups and applications, and they’re easy to use. These characteristics make op-amps extremely common in design and in real life. Web1 de nov. de 2024 · The gain of an ideal op-amp is infinity. The gain of a real, physical op-amp is more like 10,000; 100,000; or more. Let's say your 10,000 gain real op-amp is producing a output voltage of 1 volt. Then it must have a differential voltage of 100 microvolts. That's close enough for a rough analysis to call it 0. \$\endgroup\$ – cygwin encfs
