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.
