Toshiba Electronics Europe has released a lens reduction type, 5340-pixel by 3-line colour CCD linear image sensor for office automation and industrial equipment, achieving 24 lines per millimetre resolution for an A4-size document.

The TCD2569BFG offers high image quality with less colour registration by reducing the spacing between pixel arrays (red-green, green-blue). Each of the pixels in the 5340 pixel by 3-line array measures 5.25x5.25mm. A built-in sample and hold circuit lengthen the video output signal period of the sensor and contributes to easier design of high-speed scanners for use in office automation equipment and industrial equipment. Additionally, 4V saturation output voltage in the CCD shift register reduces any blooming. Installing a clipping function via a clamp circuit ensures the output signal voltage is held below 1.8V, which prevents output signal voltage from exceeding the maximum input voltage range of the analogue front-end IC. The device operates from a power supply in the range 9.5V to 10.5V and can operate at frequencies up to 35MHz.
