(December 2009) (Learn how and when to remove this template message) </Td> </Tr> <P> The open - loop gain of an amplifier is the gain obtained when no overall feedback is used in the circuit . Open loop gain, in some amplifiers, can be exceedingly high . An ideal operational amplifier has infinite open - loop gain . Typically an op - amp may have a maximal open - loop gain of around 10 5 (\ displaystyle 10 ^ (5)). The very high open - loop gain of the op - amp allows a wide range of feedback levels to be applied to achieve the desired performance . </P> <P> Normally, feedback is applied around an amplifier with high open loop gain so that the effective gain circuit is defined and kept to a desired figure . </P>
