Description:
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-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.
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
MECHANICAL INFORMATION:
This assembly consists of 2 sensor chips mounted on a printed-circuit board in a clear molded plastic package.
Notes:
A. All linear dimensions are in millimeters.
B. The true-position spacing is 2.54 mm between lead centerlines. Each pin centerline is located within 0.25 mm of its true
longitudinal positions.
C. Index of refraction of clear plastic is 1.52.
D. The gap between the individual sensor dies in the array is 57 μm typical (51 μm minimum and 75 μm maximum).
E. This drawing is subject to change without notice.
