Maybe there is no distributor in the Antartic.
Perhaps if we knew what country you were in, then maybe people could help more, an example, if you were in the UK I could point you to a chap who would answer your q's.
Alibaba for expensive ADC/DAC's what could possibly go wrong
The Antarctic (please note the spelling) is a great place for electronics design. We get the absolute best support of anyplace in the world. So I doubt you will be able to recommend a contact other than the ones I have.
You should listen very carefully when I say, there are no devices to be found in the main line supply chain. NONE. The AKM factory burned down in November and I learned about it a few days later when a broker called asking to buy my excess inventory. The supply chain has been stripped of flesh and the bones left to dry in the sun. But if you have any AK4556VT lying around let me know.
Most importantly, what question are you trying to answer? Is your chap a web developer who can explain to me why the web site doesn't work or a management consultant who can possibly give AKM some advice on how not to turn away customers?
He's in the US. I don't know why he persists with the childish Antarctica thing when he makes his location obvious in about 50% of his posts.
I display Antarctica because I thought it was fun. Yes, I'm in the US. Now, how does that impact the situation?
I would much rather be childish than to be so serious that I come across as a grouch.
