AI325 Datasheet | A1 PROs

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.
