TSL1406R Linear Array Sensor

768 x 1, with hold 400 DPI


The TSL1406R is a 400 dots-per-inch (DPI) linear sensor array consisting of two 384-pixel sections, each with its own output. The sections are aligned to form a contiguous 768 × 1 pixel array. The device incorporates a pixel data-hold function that provides simultaneous integration-start and integration-stop times for all pixels.  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 by internal logic that requires only a serial-input (SI) pulse and a clock.
