Jargon buster

Plain-language definitions for the technical terms used above.

Op-amp
An op-amp, or operational amplifier, is a chip used to amplify, buffer, or compare analogue signals. Resistor values around an op-amp help set gain and input behaviour, so choosing the right resistance matters for stable circuit performance.
