Low Power Ambient Light-to-Voltage

Non-Linear Converter

The ISL29102 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 human eyes, the photodiode array has peak

sensitivity at 550nm and spans from 400nm to 600nm,

rejecting UV light and IR light. The input luminance range is

from 0.3 lux to 10,000 lux.

The integrated non-linear current amplifier boosts and

converts the photodiode signal in a square root fashion,

extending the light input dynamic range while maintaining

excellent sensitivity at dim conditions with low lux levels. The

device consumes minimal power over a wide range of

ambient lux levels because the current consumption ramps

at a square root fashion. 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 while maintaining excellent sensitivity at low

lux levels. The built-in 1µA op amp gives the ISL29102 an

output voltage driving advantage for heavier loads.

The ISL29102 is housed in an ultra compact 2mmx2.1mm

ODFN plastic case surface mount package. Operation is

rated from -40°C to +85°C.
