ISL29125 RGB Sensors

ISL29125 RGB Sensors

Intersil's 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 50 Hz and 60 Hz 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 56 μA, which reduces to 0.5 μA 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 2.25 V to 3.63 V, I2C supply from 1.7 V to 3.63 V, and operating temperature over the -40°C to 85°C.
