what happend to my lm3886 amp?

sonicdigital · 9th April 2005, 05:29 PM

I have hardwired the LM3886 but i dont know why i didnt get the sound ive did everything exactly like in the datasheet but its not giving any music even when i connect the source ...

But one thing i get perfectly is that when i switch the amp i get a little bit louder popping sound and this happens when i switch it on and even when i turn off..

One thing that iam very doubtful is that is this CHIP is static sensitive?

Because I have touched the pins with my fingers many times while soildering. Does this damages the pin?

so LM3886 gets damaged if i touch it with fingers?

?

Hi sonicdigital, can you post your current circuit? I'd have same problem because I forgot to put Rin on pin 10 (input). When I put the R, everything sound clear.
