This lecture is centered on two main operational amplifier guidelines; 1- the voltages on the negative and positive input terminals are the same, and 2- the input currents through these terminals are essentially zero.
Starting with an overview of op amps, we continue with their voltage transfer characteristics, open loop and closed loop configurations, and inverting and non-inverting circuits. We derive for the output of the inverting and non-inverting amplifier, and talk about how amplifier rules can be used to find these outputs. Using an Analog Arts (http://analogarts.com/) SF880, we evaluate the output of an amplifier for a sine and a triangle signal. The lecture includes some common op-amp examples.
