ill ^{va Description}
t ^{The TSL1402R linear sensor array consists of two sections of 128 photodiodes each and associated charge}
amplifier circuitry, aligned to form a contiguous 256 × 1 pixel array. The device incorporates a pixel data-hold
G _{s function that provides simultaneous integration start and stop times for all pixels. The pixels measure 63.5 μm}
by 55.5 μm, with 63.5-μm center-to-center spacing and 8-μm spacing between pixels. Operation is simplified
A ^t by internal logic requiring only a serial-input pulse (SI) and a clock.
The TSL1402R is intended for use in a wide variety of applications including mark and code reading, OCR and
s ^{n contact imaging, edge detection and positioning, and optical encoding.}
