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.
