Description

The TSL201R linear sensor array consists of a 64

× 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 TSL201R 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.
