Finite gain op amp
WebNov 17, 2024 · The unity gain-bandwidth product is the frequency at which the finite loop gain becomes unity. This makes op amps behave similarly to first order low-pass filters near their GBWP. For high frequency applications, a current feedback op amp can be used. Op amps usually have low (but non-zero) output impedances. WebFor most practical op-amps the open loop DC gain A is extremely high. For example, the popular 741 has a typical open loop gain A of 200000 Vo/Vi. Some op-amps have open …
