Description

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.
