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

The ISL76671 is a low cost, light-to-voltage silicon optical

Features

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.

• 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

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.

• Internal temperature compensation

• Good IR rejection

• Low supply current

• Operating temperature range -40°C to +105°C

• 6 Ld ODFN: 2mmx2.1mmx0.7mm

• Pb-free (RoHS compliant)

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.

• AEC-Q100 Qualified

Applications

• Display backlight control - central info display and

instrumentation

• Anti-glare mirror systems - specified to operate behind Bezel

mounting

The ISL76671 is housed in an ultra compact 2mmx2.1mm

ODFN plastic surface mount package. Operation is rated from -

40°C to +105°C, Grade 2 per AEC-Q100.
