summary of Amplifier Applications

summary

Direct-coupled amplifiers are used primarily as voltage amplifiers.

● A differential amplifier has two separate inputs and may provide either one or two outputs.

● Audio amplifiers amplify AC signals in the audio range of 20 to 20,000 hertz.

● The two types of audio amplifiers are voltage amplifiers and power amplifiers.

● Video amplifiers are wideband amplifiers used to amplify video information.

● Video frequencies extend from a few hertz to 5 or

● RF amplifiers operate from 10,000 hertz to 30,000 megahertz.

● The two types of RF amplifiers are tuned and untuned.

Op-amps may provide output gains of 20,000 to 1,000,000 times the input.

● The two basic closed-loop modes are the inverting configuration and the noninverting configuration.
