ICX248AK
Diagonal 8mm (Type 1/2) CCD Image Sensor for NTSC Color Video Cameras
Description
The ICX248AK is an interline CCD solid-state
image sensor suitable for NTSC color video cameras
with a diagonal 8mm (Type 1/2) system. Compared
with the current product ICX038DNA, basic
characteristics such as sensitivity, smear, dynamic
range and S/N are improved drastically through the
adoption of EXview HAD CCDTM technology.
This chip features a field period readout system and
an electronic shutter with variable charge-storage
time. This chip is compatible with the pins of the
ICX038DNA and has the same drive conditions.
EXview HAD CCDTM has different spectral characteristics
from the current CCD.

∗4 Connect to GND or leave open.
∗5 The setting value of the substrate voltage (VSUB) is indicated on the back of the image sensor by a special
code. When adjusting the substrate voltage externally, adjust the substrate voltage to the indicated voltage.
The adjustment precision is ±3%. However, this setting value has not significance when used in substrate
bias internal generation mode.
