hi /diy/ i need some help.
i have this old ISA sound card i'm trying to fix, the chip in the red circle is blown, i assume its some kind of op-amp however i can't find any dadasheet about it.
perhaps a TEA2025B is the same thing as a CM2025B

>TEA2025B
nope, the wiring is different
If it's an op-amp just tracing the circuit will probably be easier.
>>996721
an then what ?
>>996765
Then find a modern opamp with good enough specs. It's audio, it's easy.
>>996775
you can just dump any random op amp. i would literally need another board for it, it gonna be messy as fuck.
>>996776
If you're lucky there'll be a drop in. But shit's >30 years old senpai

I think you are incorrect. I don't think you have examined this closely enough.
>>996784
i did, check the 12 and 13.
for the TEA they're positive.
>>996799
oups, nvm i didn't see the caps
>>996784
you're right.
thanks
