RGBW Color Sensor with I²C Interface
DESCRIPTION
VEML6040 color sensor senses red, green, blue, and white
light and incorporates photodiodes, amplifiers, and analog /
digital circuits into a single chip using CMOS process. With
the color sensor applied, the brightness, and color
temperature of backlight can be adjusted base on ambient
light source that makes panel looks more comfortable for
end user’s eyes. VEML6040’s adoption of Filtron^TM
technology achieves the closest ambient light spectral
sensitivity to real human eye responses.
VEML6040 provides excellent temperature compensation
capability for keeping the output stable under changing
temperature. VEML6040’s function are easily operated
via the simple command format of I²C (SMBus compatible)
interface protocol. VEML6040’s operating voltage ranges
from 2.5 V to 3.6 V. VEML6040 is packaged in a
lead (Pb)-free 4 pin OPLGA package which offers the
best market-proven reliability.
