General Description

The HDJD-J822 is a CMOS mixedsignal IC designed to be the optical feedback controller of an LED-based lighting system.

A typical system consists of an array of red, green and blue LEDs, LED drivers, a tri-color photosensor that samples the light output, and the HDJD-J822.

The IC interfaces directly to the photosensor, processes the color information and adjusts the light output from the LEDs until the desired color is achieved.
