Description

The TSLW201R linear sensor array consists of a 64

× 1 array of photodiodes, associated charge amplifier

circuitry, and a pixel data-hold function that provides simultaneous-integration start and stop times for all pixels.

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 TSLW201R 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.
