Common Erik,
don't be so awkward(:-)

1) The precision of the DS2438 is enough for the specs of original poster. What is wrong?

2) The author will get the digital temperature value so there is no need of the analog multiplexer. What is wrong?

3) This chip is designed as smart battery monitor.
There are a lot of advantages in using this chip.

That's my opinion only. What is wrong in that? If not why have you commented my post?

Regards,
George
