Operational Amplifier Tutorial & cool microphone circuit

Operational Amplifier Tutorial & cool microphone circuit Video Clips. Duration : 5.32 Mins.


Afroman goes over the basics of how to use an operational amplifier to amplify tiny voltages, and builds a circuit to listen to very faint sounds with a microphone. Don't forget to vote 5! The final microphone amplifier circuit diagram is here: www.afrotechmods.com For more information about amplifiers, Google "inverting amplifier" "non-inverting amplifier" "instrumentation amplifier" "class A amplifier" "class B amplifier" "class AB amplifier" and that should give you a lot to chew on.
