TDA2030 is a monolithic integrated circuit in Pentawatt package, intended for use as a low frequency class AB amplifier. It provides 14W output power (d = 0.5%) at 14V/4Ω at ± 14V or 28V, the ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

After seeing video of a beer can turned into a guitar amp, Robert Brenne got inspired to try his hand at home-brewing his own custom music gear out of oddball parts. A mid-20s pop-culture fan, Brenne ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

I'd like to monitor the amount of power (in watts) going into my speakers. I'm not concerned about over driving them or anything, I'm just curious how much power I'm actually using. I connected a volt ...
