1 More on Op Amps Discussion D12.1
2 Ideal Op Amp 1) The open-loop gain, A v, is infinite. 2) The current into the inputs are zero.
3 Ideal Op Amp with Negative Feedback Golden Rules of Op Amps: 1.The output attempts to do whatever is necessary to make the voltage difference between the inputs zero. 2.The inputs draw no current.
4 Non-inverting Amplifier Closed-loop voltage gain
5 Unity-Gain Buffer Closed-loop voltage gain Used as a "line driver" that transforms a high input impedance (resistance) to a low output impedance. Can provide substantial current gain.
6 Inverting Amplifier Current into op amp is zero
