Description

The TSL202R linear sensor array consists of two sections of 64 photodiodes and associated charge amplifier

circuitry arranged to form a contiguous 128

× 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 TSL202R 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.
