Ambient Light Photo Detect IC
Features
The EL7900 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.
• Monolithic IC containing photodiode and amplifier
• 1lux to 8,000lux range
• Converts light intensity to current
• 2.7V to 5.5V supply range
• Low supply current: 1µA
• Fast response time - <200µs
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.
• Excellent output linearity of luminance
• Ultra-compact and light surface mount package
• Pb-free (RoHS compliant)

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate - e3 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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
