There are many instances where a very simple to build (and relatively cheap) power amplifier is needed. The TDA2030 is a single chip amplifier capable of 14W output into 4 ohms with a few external components.

It can be used for almost any application you could think of. The power from this amplifier is very average of many amplifiers, which means it could find applications anywhere, here are just a few ideas:

* A pair can form a capable amp for a stereo system (i.e. a home made or upgraded midi system or ‘ghetto-Blaster’, although battery operation will not be possible).
* This amplifier can be used to complete surround sound systems (i.e. centre and rear channel amps). I used this amp for my centre channel in my original surround sound system. It now lays unused, waiting for a mono audio application to present itself.
* A pair can be used to improve the sound from a NICAM® TV, or even one may be used to improve a mono TV.
* Beefing up those 400W+ amps in PC speakers (seriously)!
* Tweeter or mid range amplifiers in bi-amp or tri-amp systems.
