Data Sheet November 17, 2011 ISL29001 FN6166.7 Light-to-Digital Sensor The ISL29001 is an integrated ambient light sensor with ADC and I2C interface.

With a spectral sensitivity curve matched to that of the human eye, the ISL29001 provides 15-bit effective resolution while rejecting 50Hz and 60Hz flicker caused by artificial light sources.

In normal operation, the ISL29001 consumes less than 300µA of supply current.

A software power-down mode controlled via the I2C interface disables all but
