Description

The TSL208R linear sensor array consists of a 512 × 1

array of photodiodes and associated charge amplifier

circuitry. 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 TSL208R 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.
