The speakers don't need a negative voltage relative to "ground"; they just need their inputs to vary with respect to each other. That's not why the chip became bad. Computers and Peripherals Data Center.

It would make much more sense to accept user's answer, since he very well explained tdw7297 the TDA chip became bad. General terms and conditions. Cloud Components and Modules.
TDA 15W+15W Dual Bridge Amplifier
It makes no difference. TDA amplifier board gives no sound Ask Question. Be the first to review this product.

Email to a Friend. Computers and Peripherals Data Center. If you need additional info, tell me.
Can you trace the tracks on the PC board to see where the "V" terminal connects? Then my circuit shouldn't be broken.
I have exactly this kit, dta7297 just traced out the PCB to find out how it was wired. All the answers and comments were appreciated. Product is in design stage Target: I assumed they did that, but will look at it again tomorrow. The TDA won't give any output unless you do: Not Recommended for New Design.
TDA7297 Amplifier Board / Dual-channel Noise-Free AC and DC
Personally I would just trace the entire circuit from the PCB. His answer was informative, of course. If you spend between 40 and 48 - That's not why the chip became bad. Please contact our sales support for information on specific devices. I have a small, simple circuit here. Post as a guest Name.

TDA7297 15W+15W Dual Bridge Amplifier
It did not work without it, and it did not work with yda7297. Rather, I'm using two 47K resistors. Thanks for the clue. Speakers need negative voltages as well
