TSL1402R - TAOS

TSL1402R 256 x 1 LINEAR SENSOR ARRAY WITH HOLD

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-μm center.

Features

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.
