ISL29101
FN6510.0
Small, Low Power, Voltage-Output
Ambient Light Photo Detect IC
The ISL29101 is a low power ambient Light-to-Voltage
optical sensor combining a photodiode array, a current
amplifier and a micropower operational amplifier on a single
monolithic IC. Similar to the human eye, the photodiode
array has a peak response at 550nm and spans from 400nm
to 600nm, rejecting UV light and IR light. The output voltage
is proportional to the visible light intensity from 0.5 lux up to
10,000 lux. However, the input luminance range can go up to
30,000 lux with some compromise in linearity.
A dark current compensation circuit aids the photodiode array
to minimize temperature dependent leakage currents in the
absence of light, improving the light sensity at low lux levels.
Housed in an ultra-compact surface mount 2mmx2.1mm
ODFN clear plastic package, this device is excellent for
power saving control functions in cell phones, PDAs, and
other handheld applications.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets; molding compounds/die attach materials and
NiPdAu plate - e4 termination finish, which is 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.
