ISL29003
FN7464.5
Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, Interrupt
Function and I2C Interface
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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate - e3 termination finish, which is
RoHS compliant and compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
