Ai325
1/3 inch CCD Image Sensor for EIA B/W Camera
Description
The Ai325 is a 250K pixels CCD area sensor
for EIA 1/3inch video cameras. Buried
photodiode and micro lens are adopted for low
noise, low smear and high sensitivity. This chip
also features a strong anti-blooming and
electronic shutter with variable charge-storage
time.
Feature
-. Micro Lens for high sensitivity
-. Image-lag is negligible and excellent blooming
suppression is performed.
-. TTL level(5V) operation on HCCD & RG electrodes.
-. 16 pin plastic-DIP.
-. Variable electronic shutter of 1/60 to 1/100,000 sec.
-. High sensitivity and low smear.
