Diagonal 6.28 mm (Type 1/3) CMOS Solid-state Image Sensor with Square Pixel for
Color Cameras
IMX238LQJ-C
Description
The IMX238LQJ-C is a diagonal 6.28 mm (Type 1/3) CMOS active pixel type solid-state image sensor with a square
pixel array and 1.37 M effective pixels. This chip operates with analog 3.3 V, digital 1.2 V, and interface 1.8 V triple
power supply, and has low power consumption. High sensitivity, low dark current and no smear are achieved through
the adoption of R, G and B primary color mosaic filters. This chip features an electronic shutter with variable
charge-integration time.
(Applications: Surveillance cameras, FA cameras, industrial cameras)
