Gain for an inverting op amp
WebThose extra resistors are used to set the gain of the op-amp stage. Without them the non-inverting amp has a gain of 1. While this is useful in certain applications there are many where you want more gain. For example, if you had a microphone you may want a gain of 100 or even more. Regards, APD WebThe open-loop gain of an electronic amplifier is the gain obtained when no overall feedback is used in the circuit.. The open-loop gain of many electronic amplifiers is exceedingly high (by design) – an ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around , or 100 …
