ICX255AL

Diagonal 6mm (Type 1/3) CCD Image Sensor for CCIR B/W Video Cameras

Description

The ICX255AL is an interline CCD solid-state

image sensor suitable for CCIR B/W video cameras

with a diagonal 6mm (Type 1/3) system. Compared

with the current product ICX055BL, basic

characteristics such as sensitivity, smear, dynamic

range and S/N are improved drastically from visible

light region to near infrared light region 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.

16 pin DIP (Plastic)

Features

• Sensitivity in near infrared light region

(+8dB compared with the ICX055BL, λ = 945nm)

• High sensitivity (+6dB compared with the ICX055BL, no IR cut filter)
