ISL76671 Product Details

Low Power, <100 Lux Optimized, Analog Output Ambient Light Sensor 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.

Low Power, <100 Lux Optimized, Analog Output Ambient Light Sensor

The 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 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. As such, the part is ideal for measuring incident daylight when mounted behind heavily smoked bezels used around displays or behind mirrors. The device consumes minimum power. A dark current compensation circuit minimizes the effect of temperature dependent leakage currents in the absence of light, improving the light sensitivity at low lux levels. The output gain has been optimized to require a relatively low value external bias resistor that falls within recommended automotive EMI limits. The built-in 1�A op amp gives the ISL76671 an output voltage driving advantage for heavier loads that can drive an ADC directly. The ISL76671 is housed in an ultra compact 2mmx2.1mm ODFN plastic surface mount package. Operation is rated from to +105�C, Grade 2 per AECQ100.
