The TSL1402R linear sensor array consists of two sections of 128 photodiodes each and associated charge amplifier circuitry, aligned to form a contiguous 256 x 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 m by 55.5 m, with 63.5-m center-to-center spacing and 8-m spacing between pixels. Operation is simplified 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 contact imaging, edge detection and positioning, and optical encoding.
