CCD Linear Image Sensor
MN3666A
7500-Bit High-Speed High-Resolution CCD Linear Image Sensor
Overview
The MN3666A is a high-speed high-resolution CCD linear image
sensor having low dark output floating photodiodes in the
photodetector region and CCD analog shift registers for read out. It
provides large output at a high S/N ratio for visible light inputs over a
wide range of wavelength.
Features
7500 floating photodiodes and n-channel buried type CCD shift
registers for read out are integrated in a single chip.
Use of photodiodes with a new structure has made the dark output
voltage very low.
An A3 size document can be read with a high resolution of 600dpi.
Permits high speed scanning of a data rate of 10MHz.
High blue responsivity of a maximum responsivity ratio of 60%
(typ.) at 400nm, and smooth spectral response over the entire
visible region.
A large signal output of 1400mV (typ.) can be obtained at
saturation, and the hold type waveform output makes signal
processing easy.
Operation with a single +12V positive power supply.
