FN6166.5
Light-to-Digital Sensor
The ISL29001 is an integrated ambient light sensor with
ADC and I
2
C interface. With a spectral sensitivity curve
matched to that of the human eye, the ISL29001 provides
15-bit effective resolution while rejecting 50Hz and 60Hz
flicker caused by artificial light sources.
In normal operation, the ISL29001 consumes less than
300碌A(chǔ) of supply current. A software power-down mode
controlled via the I
2
C interface disables all but the I
2
C
interface. A power-down pin is also provided, which reduces
power consumption to less than 1碌A(chǔ).
The ISL29001 includes an internal oscillator, which provides
100ms automatic integration periods, or can be externally
timed by I
2
C commands. Both the internal timing and the
illuminance resolution can be adjusted with an external
resistor.
Designed to operate on supplies from 2.5V to 3.3V, the
ISL29001 is specified for operation over the -40擄C to +85擄C
ambient temperature range. It is packaged in a clear 6 Ld
ODFN package.

NOTE: Intersil Pb-free 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.
