Yes, this helps alot! Thanks a million. On a totally different note - are there any plans that you can share about an A to D with more bits. Maybe a 12-bit? Or, if you guys would just make the reference voltage on the 62X line 10 or 12 bits (with 2^10 or 2^12 possible combinations too - the current version is 8-bit but doesn't give 2^8 voltage values). > Paul, the power up timers work as follows: > > Hope this helps.
