| (R) ISL29000 Data Sheet June 20, 2005 FN6117.0 PRELIMINARY 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. Features * Monolithic IC containing photodiode and amplifier * Converts light intensity to current * 2.5V to 5.5V supply range * Low supply current - 1A * Excellent output linearity of luminance * Ultra-compact and light surface mount package * Pb-Free plus anneal available (RoHS compliant) Applications * Mobile phones * Notebook PCs * PDAs * Video cameras * Digital cameras Pinout ISL29000 (5-PIN DFN) TOP VIEW VCC OUTPUT Ordering Information PART NUMBER ISL29000IROZ (See Note) PACKAGE 5-Pin ODFN (Pb-free) TAPE & REEL PKG. DWG. # MDP0052 GND EN NC 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. 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
