Ambient Light Sensor
ISL76671
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. 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 1μA 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
