The ISL29112 is a low cost, light-to-voltage silicon optical sensor combining a photodiode array, a non-linear current amplifier, and a micropower op amp on a single monolithic IC. Similar to the human eye, the photodiode array has peak sensitivity at 550nm and spans the wavelength range 400nm to 600nm, rejecting UV and IR light. The input luminance range is from 0.01 lux to 100 lux.The integrated non-linear current amplifier boosts and converts the photodiode signal into a square root output format, extending dynamic range while maintaining excellent sensitivity in dimly lit conditions.
Square root voltage output 0.01 lux to 100 lux range 1.8V to 3V supply range Close to human eye spectral response Fast response time Internal temperature compensation Good IR rejection Low supply current Operating temperature range -40°C to +85°C 6 Ld ODFN: 2mmx2.1mmx0.7mm Pb-free
