DATASHEET ISL29125 FN8424 Rev.3.00 Digital Red, Green and Blue Color Light Sensor with IR Blocking Filter Jan 13, 2017 The ISL29125 is a low power, high sensitivity, RED, GREEN and Features 2 BLUE color light sensor (RGB) with an I C (SMBus compatible) 56A operating current, 0.5A shutdown current interface. Its state-of-the-art photodiode array provides an 2 accurate RGB spectral response and excellent light source to Selectable range (Via I C) light source variation (LS2LS). The ISL29125 is designed to 2 I C (SMBus compatible) output reject IR in light sources allowing the device to operate in ADC resolution 16 bits environments from sunlight to dark rooms. The integrating ADC rejects 50Hz and 60Hz flicker caused by artificial light Programmable interrupt windows sources. A selectable range allows the user to optimize Two optical sensitivity ranges sensitivity suitable for the specific application. In normal - Range 0 = 5.7m lux to 375 lux operation mode the device consumes 56A, which reduces to 0.5A in power-down mode. The ISL29125 supports hardware - Range 1 = 0.152 lux to 10,000 lux and software user programmable interrupt thresholds. The Operating power supply 2.25 to 3.63V Interrupt persistency feature reduces false trigger notification. 2 2 I C power supply 1.7V to 3.63V The device operates on supplies (VDD) from 2.25V to 3.63V, I C supply from 1.7V to 3.63V, and operating temperature across the 6 Ld ODFN (1.65x1.65x0.7mm) package -40C to +85C range.
