Light-to-Digital Output Sensor with High
Sensitivity, Gain Selection, Interrupt
Function and I
2
C Interface
The ISL29003 is an integrated light sensors with a 16-bit
integrating type ADC, I
2
C user programmable Lux range
select for optimized counts/Lux, and I
2
C 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 300碌A(chǔ).
Furthermore, an available software power-down mode
controlled via the I
2
C interface reduces power consumption
to less than 1碌A(chǔ).
The ISL29003 supports a hardware interrupt that remains
asserted low until the host clears it through I
2
C interface.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29003 is specified for operation over the -40擄C to +85擄C
ambient temperature range.

NOTE: Intersil Pb-free ODFN products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are 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.
