CCD Linear Image Sensor
MN3646
2880-Bit High-Responsivity CCD Linear Image Sensor
Overview
The MN3646 is a 2880-pixel high sensitivity CCD linear image
sensor combining photo-sites using low dark output floating
photodiodes 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
2880 floating photodiodes and n-channel buried type CCD shift
registers for read out are integrated in a single chip.
Operates on +5V single power supply and can driven by 5V CMOS
logic.
Use of photodiodes with a new structure has made the dark output
voltage very low.
Has a smooth spectral response that is close to the sensitivity of the
human eye in the entire visible region.
Large signal output of typically 1200mV at saturation can be
obtained.
Since a compensation output pin (DS) is provided in addition to the
signal output pin (OS), it is possible to obtain a signal with a high
S/N ratio by carrying out differential amplification of the OS and
DS outputs.
