DATASHEET ISL29009 FN6484 Rev 0.00 Non-Linear Output Current, Low Power Ambient Light Photo Detect IC July 1, 2008 The ISL29009 is a light-to-current silicon optical sensor Features combining a photodiode and current amplifiers on a single Non-linear current output monolithic IC. Similar to human eyes, the photodiode has peak sensitivity at 550nm and spans from 400nm to 700nm, 0.3 lux to 10,000 lux range rejecting UV light and IR light. The input luminance range is Dark current compensation from 0.3 lux to 10,000 lux. Temperature compensated The integrated non-linear current amplifier boosts and converts Human eye response the photodiode signal in a square root fashion, extending the light input dynamic range while maintaining excellent sensitivity 1.8V to 3.3V supply range at dim conditions with low lux levels. The device consumes Low supply current minimal power over a wide range of ambient lux levels because the current consumption ramps at a square root fashion. A dark Fast response time current compensation circuit aids the photodiode to minimize 6 Ld ODFN: 2mmx2.1mmx0.7mm temperature dependent leakage currents in the absence of Pb-free (RoHS compliant) light, improving the light sensitivity at low lux levels. In addition, the ISL29009 has an EN pin that can be used for Applications a polling scheme extending portables battery life. Display and keypad dimming for: The ISL29009 is housed in an ultra compact 2mmx2.1mm - Mobile devices: smart phone, PDA, GPS ODFN plastic case surface mount package.
