Hi All!!! 
I'm new to this forum and this is my first post.
I would like to know if anyone out there could help me with my TDA1553 chips. I got about 30 of these IC's for free at a friend who works at a electronics shop. I don't have a problem designing a amp for this IC, the problem that I have is that those that I got are 18 pins and I have no idea what the pin outs are!!
Can someone please help me with this one, as I cannot find a datasheet for the 18 pin chips? They are made by Phillips.
Thanx
