Description
The TSL208R linear sensor array consists of a 512 ?1
array of photodiodes and associated charge amplifier
circuitry. The pixels measure 120 糾 (H) by 70 糾 (W)
with 125-糾 center-to-center spacing and 55-糾
spacing between pixels. Operation is simplified by
internal control logic that requires only a serial-input (SI)
signal and a clock.
The TSL208R is intended for use in a wide variety of applications including mark detection and code reading,
optical character recognition (OCR) and contact imaging, edge detection and positioning as well as optical linear
and rotary encoding.
