DATASHEET ISL29101 FN6510 Rev 1.00 Small, Low Power, Voltage-Output Ambient Light Photo Detect IC November 5, 2012 The ISL29101 is a low power ambient Light-to-Voltage Features optical sensor combining a photodiode array, a current 0.5 lux to 10,000 lux range amplifier and a micropower operational amplifier on a single monolithic IC. Similar to the human eye, the photodiode 1.8V to 3.3V supply range array has a peak response at 550nm and spans from 400nm Low supply current to 600nm, rejecting UV light and IR light. The output voltage Fast response time 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 Excellent linearity of output voltage vs light intensity 30,000 lux with some compromise in linearity. Close to human eye response A dark current compensation circuit aids the photodiode array Good IR rejection to minimize temperature dependent leakage currents in the absence of light, improving the light sensity at low lux levels. Internal temperature compensation Housed in an ultra-compact surface mount 2mmx2.1mm Operating temperature range -40C to +85C ODFN clear plastic package, this device is excellent for Ultra-compact surface mount package power saving control functions in cell phones, PDAs, and Pb-free (RoHS compliant) other handheld applications.
