Hi
I need a (common) equivalent for the following IC's
βA758
βA723
βM3189
You can see the β symbol , it was from the old now-buried electronic parts factory from the former Socialist Republic of Romania .
I found in an old equivalent book the following IC's :
βA758 = LM758
βA723 = LM723
βM3189 = LM3189 = CA3189 = TCA3189
LM723 is easy to find
LM758 is a lot harder to find (in my region )
and
The most important IC is the LM3189 , it is part of a FM-IF system
Is there a common equivalent for the 758 and 3189 IC's ?
Schematic of the FM-IF system: (it is in romanian but you can understand how it works)
