VEML6040
www.vishay.com Vishay Semiconductors RGBW Color Sensor with I2C Interface
FEATURES Package type: surface mount Dimensions (L x W x H in mm): 2.0 x 1.25 x 1.0 Integrated modules: color sensor (RGBW) and signal conditioning IC FiltronTM technology provides a spectrum matching real human eye responses Supports low transmittance (dark) lens design Fluorescent light flicker immunity Provides 16-bit resolution for each channel (R, G, B, W) 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. Selectable maximum detection range (360, 721, 1442, 2883, 5767, or 11 796) lux with highest sensitivity 0.0056 lux/step Package: OPLGA Temperature compensation: -40 °C to +85 °C Low power consumption I2C (SMBus compatible) interface Output type: I2C bus Operation voltage: 2.5 V to 3.6 V Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS Handheld device Notebook Consumer device Industrial and mechanical application PRODUCT SUMMARY
