Diagonal 8mm (Type 1/2) CCD Image Sensor for EIA B/W Video Cameras
Description
The ICX428ALB is an interline CCD solid-state
image sensor suitable for EIA B/W video cameras
with a diagonal 8mm (Type 1/2) system. 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. Also, this outline is miniaturized by using
original package. This chip is compatible with the
pins of the ICX248ALB and has the same drive
conditions.
EXview HAD CCDTM has differrent spectral
characteristics from the curreent CCD.

∗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.
