VEML6040
Vishay Semiconductors
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 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.

RECOMMENDED IRON TIP SOLDERING CONDITION AND WARNING HANDLING
1. Solder the device with the following conditions:
1.1. Soldering temperature: 400 °C (max.)
1.2. Soldering time: 3 s (max.)
2. If the temperature of the method portion rises in addition to the residual stress between the leads, the possibility that an
open or short circuit occurs due to the deformation or destruction of the resin increases.
3. The following methods: VPS and wave soldering, have not been suggested for the component assembly.
4. Cleaning method conditions:
4.1. Solvent: methyl alcohol, ethyl alcohol, isopropyl alcohol
4.2. Solvent temperature < 45 °C (max.)
4.3. Time: 3 min (min.)
