The Agilent ADJD-J823 is a CMOS mixed-signal integrated circuit designed as an optical feedback device for RGB LED-based backlighting systems. It features integrated RGB photosensors, an analog-to-digital converter, color data processing logic, and a 12-bit PWM output generator. This controller samples light output, processes color information, and adjusts RGB LED output to achieve target colors, ensuring color stability over time and temperature. It supports color specification via the CIE color space through a serial interface and offers adjustable light sensitivity. The device is ideal for LCD backlighting applications.
