I tried DS2450 - and decided NEVER use it again.
It is a very low quality AD converter. Read values are jumping very much,
and I could not fix it by oversampling. Even using 100x oversampling the
read voltage was jumping a lot.
Comparing to MCP3008 SLI interface AD converter it is a crap. (MCP3008 is
also "jumping " +-1 value, but with 10x times oversampling it can be fixed
quite well - while DS2450 was not able to reach it even with 100x
oversampling)
Datasheet tells that DS2450 is ONLY a 8 bit AD, 2 least significant bits
arejust a "guess" - take this into consideration as well.
As I know there are other chips (battery monitor, I can't recall its name)
what can be used for AD conversion on 1wire bus - but I never tried these
