#210 AudioAmps/TDA7297Kit

Testing a TDA7297 audio amplifier kit (Pump Up the Jam)

TDA7297Kit

Notes

This is a super cheap amplifier kit built around the TDA7297 15+15W dual bridge amplifier chip. All the other parts in the kit are essentially the basic supporting components for the TDA7297.

Performance is very good, although my impromptu speaker boxes don’t do it justice. They need better baffles at least, but I can hardly blame Straits Preserves for not making marmalade boxes to the specification of speaker enclosures!

TDA7297Kit_build_case

The circuit is very close to the examples in the datasheet app notes, using the “Stand-alone Low-cost Application” method of managing standby and mute inputs. The TDA7297 is a very easy ship to work with.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
