I am just trying to verify a claim made my Eric. I don't see anything wrong with that. I don't know why he wouldn't cooperate in someone verifying his claim unless it is not true
Charles,
Please verify your claim that the power companies still adjust clocks. Please verify your claim that the circuit you published for an analog multiplexer works (which it does not for the stated problem). Do you really want me to reply 'please verify your claim to every post you make - oh, sorry, I forgot, you are perfect.
PS if you are going to insult me, at least spell my name correctly.

In case some innocent soul out there believe that Charles posts contain anything but bitterness and hot air, I will forward the entire e-mail to Steve Taylor and if you doubt the above statement, contact Steve.

Kai,
If you tell us about a heavy failure of certain chip, then there must also be some way of verifying it. Imagine, that I make a post, telling all people, that I was warned that certain product of your company is a heavy misconstruction. Then, you would be the first who wants to verify it, wouldn't you?
I did not "tell us about a heavy failure of certain chip" I specifically stated that my supplier had reported to me "about a heavy failure of certain chip"

By the way, I would never publish a business mail in some public forum.
Which is exactly why I published an extract.

As to the posts re Circuit vs chip as reason for failure:
It is an absolute fact thet the circuit design has an effect on the performance of the supervisor. When we had the old layout of the board with 1" traces from the 1232 to the decoupling cap, the Microchip failure was 80% or more, soldering a decoupling cap directly across the 1232 took care of it. However the MAX chips functioned beautifully without the extra cap. Now with a new PCB layout where the traces to the decoupling cap are as short as possible, the Microchip failure is reduced, but still too high. My guess is that the problems are due to the MC1232 being extremely more noise sensitive than the MAX. I have yet to try the LTC, but my supplier is going to make 100 boards with it and we will see.
