Sure, but it's not free. You're paying for it in every part you buy. Large customers can't afford the premium, though we still get the service from other suppliers.
The TI linear/power FAE is just as good as the LT FAE (both are excellent). We're the only customer for the TI linear FAE so he's there to help almost every day (and take us out to lunch ;-). I see the LT folks every couple of months but, then, I don't use any of their parts (other coworkers do use a few). The ADI FAEs are also very good but at different things.
