Any of you knowledgeable folks know what the difference between the chip tda4605 and the versions I can find have -2 at the end.
E.g.
Tda4605-2, tda4605-3 or tda4605-15

Its an ic power driver in a monitor, I have tried to compare the data sheets between the various versions and can't see any obvious difference.
If it was an eeprom the number would be speed in ms. But it's not an eeprom so unsure.

Thanks
Ted
