Overview: 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 the I2C interface. A power-down pin is also provided, which reduces power consumption to less than 1µA.
The ISL29001 includes an internal oscillator, which provides 100ms automatic integration periods, or can be externally timed by I2C mands. Both the internal timing and the illuminance resolution can be adjusted with an external resistor.
Designed to operate on supplies from 2.5V to 3.3V, the ISL29001 is specified for operation over the -40°C to +85°C ambient temperature range. It is packaged in a clear 6 Ld ODFN package.
