Description
The TSL210 linear sensor array consists of five
sections of 128 photodiodes, each with
associated charge amplifier circuitry, running from
a common clock. These sections can be
connected to form a contiguous 640
×
1 pixel
array. Device pixels measure 120
μm
(H) by
70
μm
(W) with 125-μm center-to-center pixel
spacing. Operation is simplified by internal logic
that requires only a serial input (SI1 through SI5)
for each section and a common clock for the five
sections.
The device is intended for use in a wide variety of
applications including contact imaging, mark and
code reading, bar-code reading, edge detection
and positioning, OCR, level detection, and linear
and rotational encoding.
