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 FiltronTM

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.
