The ISL29125 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 ISL29125 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 ISL29125 supports hardware

and software user programmable interrupt thresholds. The

Interrupt persistency feature reduces false trigger notification.

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.
