Op Amp Types And Applications. A differential amplifier a voltage amplifier and a push pull amplifier. These op amp circuits may be used in applications where a single frequency or a small band of frequencies need to be removed.
One application might be for removing a line mains hum from an audio signal. These filters can be realised using a single op amp. Amplification the amplified output signal from the op amp is the difference between the two input signals.
These filters can be realised using a single op amp.
This is a basic differential amplifier which consists of three terminals. Here it provides high input impedance low output impedance. It is good at the conditioning of the signals as well as it is utilized for the amplification of the voltage signals. The applications of op amp are voltage follower comparator active filter etc.
