DATASHEET To request the full datasheet, please visit www.intersil.com/products/isl29124 Digital Red, Green and Blue Color Light Sensor with IR Blocking Filter ISL29124 Features The ISL29124 is a low power, high sensitivity, Red, Green, and Blue color light sensor (RGB) with an I2C (SMBus compatible) interface. Its state-of-the-art photodiode array provides an accurate RGB spectral response and excellent light source to light source variation (LS2LS). The ISL29124 is designed to reject IR in light sources allowing the device to operate in environments from sunlight to dark rooms. The integrating ADC rejects 50Hz and 60Hz flicker caused by artificial light sources. A selectable range allows the user to optimize sensitivity suitable for the specific application. In normal operation mode the device consumes 56µA, which reduces to 0.5µA in power-down mode. The device operates on supplies (VDD) from 2.25V to 3.63V, I2C supply from 1.7V to 3.63V, and operating temperature over the -40°C to +85°C ambient temperature range. • 56µA operating current, 0.5µA shutdown current • Selectable range (via I2C) • I2C (SMBus compatible) output • ADC resolution 16 bits • Two optical sensitivity ranges - Range 0 = 5.7 mlux to 375 lux - Range 1 = 0.152 lux to 10,000 lux • Operating power supply 2.25V to 3.63V • I2C power supply 1.7V to 3.63V • 4 Ld Optical COB (2.00x1.25mm) package Applications • Smart phone, PDA, GPS, tablet PCs, LCD-TVs, digital picture frames, digital cameras • Dynamic display color balancing • Printer color enhancement • Industrial/commercial LED lighting color management • Ambient light color detection/correction • OLED display aging compensation C1 Vbus R1 C2 VDD R2 R3 4 VDD SDA 2 SDA SCL 3 SCL MCU ISL29124 R1 – 100 R2 – 2.7k to 10k R3 – 2.7k to 10k C1 – 1µF C2 – 0.1µF GND 1 FIGURE 1.
