Description
The TSL1410R linear sensor array consists of two
sections of 640 photodiodes, each with
associated charge amplifier circuitry, aligned to
form a contiguous 1280 ?1 pixel array. The device
incorporates a pixel data-hold function that
provides simultaneous-integration start and stop
times for all pixels. The pixels measure 63.5 糾 by
55.5 糾 with 63.5-糾 center-to-center spacing
and 8-糾 spacing between pixels. Operation is
simplified by internal logic that requires only a
serial-input (SI) pulse and a clock.
The device is intended for use in a wide variety of applications including mark and code reading, OCR and
contact imaging, edge detection and positioning, and optical encoding.
