2048-Bit High-Responsivity CCD Linear Image Sensor
with Internal Clock Driver
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.
registers for read out are integrated in a single chip.
device using CMOS or TTL 5V logic.
obtained.
makes si gnal processing easy.
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.
2048 floating photodiodes and n-channel buried type CCD shift
Since a clock driver circuit is built in, it is possible to drive this
Large signal output of typically 1500mV at saturation can be
Because a sample hold circuit is built in, the output waveform
Since a compensation output pin (DS) is provided in addition to the
Operation with a single +12V positive power supply.
