What is an Operational Amplifier?

 

1) Differential amplifier - amplifies difference between two signals.

2) Can amplify very small voltage signals to a useful level.

3) Typically an 8 lead IC.

4) Op Amps can require one power supply (single supply) or a positive and a negative power supply (dual supply)
