Description

The TSL2014 linear sensor array consists of two

sections of 448 photodiodes and associated charge

amplifier circuitry that can be connected to form a

contiguous 896

× 1 array. The pixels measure 120 μm

(H) by 70

μm (W) with 125-μm center-to-center spacing

and 55-

μm spacing between pixels. Operation is

simplified by internal control logic that requires only a

serial-input (SI) signal and a clock.

The TSL2014 is intended for use in a wide variety of

applications including mark detection and code

reading, optical character recognition (OCR) and

contact imaging, edge detection and positioning as well

as optical linear and rotary encoding.
