MT-044: Op Amp Open Loop Gain and Open Loop
... Open-loop voltage gain, usually called AVOL (sometimes simply AV), for most voltage feedback (VFB) op amps is quite high. Common values are 100,000 to 1,000,000, and 10 or 100 times these figures for high precision parts. Some fast op amps have appreciably lower open-loop gain, but gains of less tha ...
