HDJD-J822 - Agilent HDJD-J822-SCR00 Color Management System Feedback Controller

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.

Features

  • 40 to 85°C operation.
  • I2C serial interface.
  • Robust CMOS-Schmitt input.
  • CMOS/TTL compatible output.
  • Multiple color input formats.
  • CIE XYZ, Yxy, Yu’v’ and RGB.
  • 3-channel analog interface to color sensor.

Agilent HDJD-J822-SCR00 Color Management System Feedback Controller Data Sheet www.DataSheet4U.com 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. To achieve this, the IC integrates a high-accuracy 10-bit analog-todigital converter front-end, a color data processing logic core, and a high-resolution 12-bit PWM output generator.
