Description

The ICX278AL is an interline CCD solid-state image sensor suitable for EIA B/W video cameras with a diagonal 4.5mm (Type 1/4) system. Compared with the current product ICX208AL, basic characteristics such as sensitivity, smear and dynamic range 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. The package is a 10mm-square 14-pin DIP (Plastic).
