tropicalrips 0 Report post Posted November 15, 2003 found this in SLS today the layout looks very close to a Cmoy, but with some things missing like input caps its ment to be an amp for speakers i think, but maybe can be converted into headphone amp? the kit comes with a TDA2822 is this also an op-amp? all the components are included price $13 anyone tried this before?

Firefox 0 Report post Posted November 16, 2003 The TDA2822 is a audio power amplifier. Somewhat like the LM386 commonly used in many soundcards. Also similar to the LM3875 used in Gainclones. It's not very suitable for headphones use though. The specs are relatively crappy to begin with. Share this post Link to post Share on other sites
