HOW TO GET INFORMATION FROM ANALOG DEVICES
Analog Devices publishes data sheets and a host of other technical literature
supporting our products and technologies. Follow the instructions below for
worldwide access to this information.
FOR DATA SHEETS
U.S.A. and Canada
■
Fax Retrieval. Telephone number 800-446-6212. Call this number
and use a faxcode corresponding to the data sheet of your choice
for a fax-on-demand through our automated AnalogFax™ system.
Data sheets are available 7 days a week, 24 hours a day.
Product/faxcode cross reference listings are available by calling
the above number and following the prompts. There is a short
index with just part numbers, faxcodes, page count and revision
for each data sheet (Prompt # 28). There is also a longer index sorted by
product type with short descriptions (Prompt #29).
