What is an Op-amp ? An op-amp is a type of amplifier – an operational amplifier. It takes in one or more voltages ( V1 and V2 ) and processes them, giving out another voltage ( Vout ). Depending on how it is connected up, the op-amp seems to carry out mathematical operations such as addition, subtraction etc.

The Op-Amp Symbol +Vs Inverting input - Output Non-inverting input + -Vs The Op-Amp needs a power supply to make it work. This is represented by Vs. The power supply connections are often missed out in diagrams.

**Power Supplies for Op-Amps**

The power supplies used with Op-Amps are a bit unusual. They are set up to have a positive terminal and a negative terminal and a zero volts terminal between the two. The zero volts terminal acts as a reference voltage when making measurements.
