ICX418ALB

Diagonal 8mm (Type 1/2) CCD Image Sensor for EIA B/W Video Cameras

Description

The ICX418ALB is an interline CCD solid-state image sensor suitable for EIA B/W video cameras with a diagonal 8mm (Type 1/2) system. Compared with the current product ICX038DLB, basic characteristics such as sensitivity, smear, dynamic range and S/N are improved drastically.

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 ICX038DLB and has the same drive conditions.

Features

• High sensitivity (+5.0dB compared with the ICX038DLB)

• Low smear (–5.0dB compared with the ICX038DLB

• High D range (+2.0dB compared with the ICX038DLB)

• High S/N

• High resolution and low dark current

• Excellent antiblooming characteristics

• Continuous variable-speed shutter

• Substrate bias: Adjustment free (external adjustment also possible with 6 to 14V)

• Reset gate pulse: 5Vp-p adjustment free (drive also possible with 0 to 9V)

• Horizontal register: 5V drive

• Maximum package dimensions: φ13.2mm

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.
