MN3644D
2048-Bit High-Responsivity CCD Linear Image Sensor
with Internal Clock Driver
Overview
The MN3644D is a high responsivity CCD linear image sensor
having floating photodiodes in the photodetector region, CCD analog
shift registers for read out, and a built-in clock driver.
It provides large output at a high S/N ratio for visible light inputs over
a wide range of wavelength.
Features
2048 floating photodiodes and n-channel buried type CCD shift
registers for read out are integrated in a single chip.
Since a clock driver circuit is built in, it is possible to drive this
device using CMOS or TTL 5V logic.
Large signal output of typically 1500mV at saturation can be
obtained.
Because a sample hold circuit is built in, the output waveform
makes si gnal processing easy.
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.
Operation with a single +12V positive power supply.
