ISL29125
Digital Red, Green and Blue Color Light Sensor with IR Blocking Filter
FN8424
Rev.3.00
Jan 13, 2017
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 across the
-40°C to +85°C range.
