Small, Low Power, Voltage-Output Ambient Light Photo Detect ICThe ISL29101 is a low power ambient Light-to-VoltageopTIcal sensor combining a photodiode array, a currentamplifier and a micropower operaTIonal amplifier on a singlemonolithic IC. Similar to the human eye, the photodiodearray has a peak response at 550nm and spans from 400nmto 600nm, rejecTIng UV light and IR light. The output voltageis proporTIonal to the visible light intensity from 0.5 lux up to10,000 lux. However, the input luminance range can go up to30,000 lux with some compromise in linearity.A dark current compensation circuit aids the photodiode arrayto minimize temperature dependent leakage currents in theabsence of light, improving the light sensity at low lux levels.Housed in an ultra-compact surface mount 2mmx2.1mmODFN clear plastic package, this device is excellent forpower saving control functions in cell phones, PDAs, and other handheld applications.
