Ambient Light Photo Detect IC

The ISL29000 is a light-to-current optical sensor combining
a photodiode and a current amplifier on a single monolithic
IC. Output current is directly proportionate to the light
intensity on the photodiode. Its sensitivity is superior to that
of a phototransistor and exhibits little variation. Its spectral
sensitivity matches closely to the luminous efficiency and
linearity.

Housed in an ultra-compact surface mount clear plastic
package, this device is excellent for power saving control
function in cell phones, PDAs, and other handheld
applications.

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.
