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).

Features

• Sensitivity in near infrared light region

(+5dB compared with the ICX208AL, λ = 945nm)

• High sensitivity (+6dB compared with the ICX208AL, no IR cut filter)

• Low smear (–20dB compared with the ICX208AL)

• High D range (+2dB compared with the ICX208AL)

• Horizontal register: 3.3 to 5V drive

• Reset gate: 3.3 to 5V drive

• No voltage adjustment (Reset gate and substrate bias are not adjusted.)

• High resolution and low smear

• Excellent antiblooming characteristics

• Continuous variable-speed shutter

• Recommended range of exit pupil distance: –20 to –100mm
