Diagonal 6.09 mm (Type 1/3) CMOS Solid-state Image Sensor with Square Pixel for

Color Cameras

IMX225LQR-C

Description

The IMX225LQR-C is a diagonal 6.09 mm (Type 1/3) CMOS active pixel type solid-state image sensor with a square

pixel array and 1.27 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.
