DATASHEET ISL76671 Low Power, <100 Lux Optimized, Analog Output Ambient Light Sensor FN7716 Rev.4.0 May 21, 2021 The ISL76671 is a low cost, light-to-voltage silicon optical sensor combining a photodiode array, a non-linear current amplifier and a micro-power 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.
