Re: Regarding LT1521-5


 

I explained this to him on March 26th when he asked the same exact question. ?Kumar does not seem to learn.

As a Linear Tech internal Senior Applications engineer located at the factory for 14 years who trained FSE/FAE, a schematic would never be allowed to leave the company. ? As a regular conduct of business, ?even applications engineers never saw a schematic too. ? Not that they could not see it. ?It just that in most cases unless there was some difficult debug involved during IC development, there was never any need to. ? Internal application engineers could simply talk to the IC designer on the phone at any time and get all the info they needed. ? FAE's would have even a harder time getting any such information since they are not really allowed to talk to the IC designers for common customer support issues. ?The are supposed to go to the internal applications people first for support. ?The goal it to keep the IC designer designing IC's and not get caught up in everyday support issues.

Linear does not allow its IC to go into any medical product that involves life support. ?It is a liability issue Linear does not want to accept. ?If there is medical application involved, John is correct that discussing it with a sales engineer would be advisable to see if Linear will allow it.

The information you require is almost certainly confidential. You should
explain your requirements to your Field Service Engineer or other formal
contact at LT. In any case, you need to discuss the use of ANY
electronic device in an implanted device with the manufacturer.
