I need a datasheet about TDA440.

Yes I know that is an old TV IF chip. I tried a google search without useable result. I need a pin description. I want to know what is inside. I have 10 chips at home, and I must build an IF circuit replacing the older one.

If it's any help, Grundig used to use the chip in some of their old sets, I'll see if I can find a circuit tomorrow that uses it.

Are you trying to build an IF that uses the 440, or one to replace a 440 IF?.

I'll try to build an IF module using the TDA440 (I have it at home). The old version is built with 4 chips.
 
:D Hi Sebi. Thank you for your help. The IC internal schematic is very useful for me. Special tanks for the IC applications.

:!: If you need something, do not hesitate to ask.

:D Köszi !
