The TH7813 and TH7814 linear arrays are based on Atmel’s most recent know-how in
terms of design and technology. Flexibility and performance of these devices give the
opportunity to use them in most vision systems for industrial applications (web inspec-
tion, process control, sorting and inspection of various parts), document scanning up
to 200 dpi, metrology, etc.
