Light-to-Digital Output Sensor with
Address Selection, High Sensitivity, Gain
Selection, Interrupt Function and I

C
Interface
The ISL29004 is an integrated light sensor 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 typically 300碌A(chǔ).
Futhermore, an available software power-down mode
controlled via the I
2
C interface reduces power consumption
to less than 1碌A(chǔ). The device also support a hardware
interrupt that remains asserted low until the host clears it
through I
2
C interface.
The ISL29004 is in an 8 Ld ODFN package and has two I
2
C
address pins for multiple devices on the same bus. The
ISL29003 is a similar light sensor with a hardwired I
2
C
address that is available in ODFN6 package.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29004 are specified for operation over the -40擄C to
+85擄C ambient temperature range.

NOTE: Intersil Pb-free plus anneal 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.
