Thanks for the correction. (I've been using the DS18S20 in another project
and forgot to switch my head back to the right chip.)
I have data sheets for the DS1620 from 053105 and 072099. The text on the
fancy temperature conversion looks the same.
The difference might be at the command/register level. I took a quick scan
and didn't see any differences.
Is 072099 old enough? Does anybody know what the critical differences is?
These are my opinions, not necessarily my employer's. I hate spam.
