ISL29001

Light-to-Digital Sensor

The ISL29001 is an integrated ambient light sensor with

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

300µA of supply current. A software power-down mode

interface. A power-down pin is also provided, which reduces

power consumption to less than 1µA.

The ISL29001 includes an internal oscillator, which provides

100ms automatic integration periods, or can be externally

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°C to +85°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.
