TSL1402R Linear Array Sensor

256 x 1, with hold 400 DPI


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 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-ìm center-to-center spacing and 8-µm spacing between pixels. Operation is simplified by internal logic requiring only a serial-input pulse (SI) and a clock.
