ISL29125
The ISL29125 is a low power, high sensitivity, RED, GREEN,
and BLUE color light sensor (RGB) with an I
2
C (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, I
2
C supply from 1.7V to 3.63V, and operating
temperature over the -40°C to +85°C.
