These devices combine a photodiode and a transimpedance amplifier on a single monolithic CMOS integrated circuit with a color filter over the photodiode.
Output voltage is directly proportional to light intensity (irradiance) on the photodiode.
Each device has a transimpedance gain of 320 MΩ with improved offset voltage stability and low power consumption, and is supplied in a 3-lead clear plastic sidelooker package with an integral lens.
These devices are ideal for applications such as colorimetry, printing process control, display color correction, and selectively ambient light detection or rejection.
