description
The TSL1301 linear sensor array consists of a 102 × 1 array of photodiodes, associated charge amplifier
circuitry, and a pixel data-hold function that provides simultaneous-integration start and stop times for all pixels.
The pixels measure 85 µm by 77 µm with 85-µm center-to-center spacing and 8-µm spacing between pixels.
Operation is simplified by internal control logic that requires only a serial-input pulse (SI) and a clock.
The TSL1301 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.
