Operational Amplifier LM324 and super microphone circuit

1403

Operational Amplifier LM324 and super microphone circuit, 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.

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.

  1. I put this circuit together but I didn’t have the 5k resistor so I used a 1k resistor. But it didn’t work so I’ll try to find a 5k and test it out again.
