Hi everyone,
I am doing a bit of a research for some content on the above chip.
every time I have worked on one of these card there was only ever a 5534, but in the schematics it calls for a TDA.
I believe it's a TDA 1034 as with a google search I have found the datasheet that matches the 5534...
anyone knows more about it and the history of why the TDA was in the schematic?
