The ISL29003 is an integrated light sensors with a 16-bit

integrating type ADC, I2C user programmable lux range

select for optimized counts/lux, and I2C multi-function control

and monitoring capabilities. The internal ADC provides 16-bit

resolution while rejecting 50Hz and 60Hz flicker caused by

artificial light sources.

In normal operation, power consumption is less than 300μA.

Furthermore, an available software power-down mode

controlled via the I2C interface reduces power consumption

to less than 1μA.

The ISL29003 supports a hardware interrupt that remains

asserted low until the host clears it through I2C interface.

Designed to operate on supplies from 2.5V to 3.3V, the

ISL29003 is specified for operation over the -40°C to +85°C

ambient temperature range.
