Product Description
TOSHIBA CCD Linear Image Sensor TCD1254GFG
The TCD1254GFG is a high-sensitivity, low dark current 2500-element CCD linear image sensor. It features an electronic shutter function (ICG) that maintains a constant output voltage regardless of light intensity variations, making it suitable for applications requiring stable imaging. This device utilizes a high-sensitivity PN photodiode for photo sensing and includes an internal CCD drive circuit and a sample and hold circuit.
