Why can't TDA2005R and TDA2005 be replaced? The problem now is that after replacing TDA2005R with TDA2005, the power supply voltage cannot exceed 8v. After exceeding, the chip heats up and there is a rattling sound, but the voltage on the pdf of tda2005 can be 8-18v. Also, I read the pdf of TDA2005R and came out The data is also TDA2005?
It is so strange.
All the best!
