Non-Linear Output Current, Low Power

Ambient Light Photo Detect IC

The ISL29009 is a light-to-current silicon optical sensor

combining a photodiode and current amplifiers on a single

monolithic IC. Similar to human eyes, the photodiode has

peak sensitivity at 550nm and spans from 400nm to 700nm,

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 aids the photodiode to minimize

temperature dependent leakage currents in the absence of

light, improving the light sensitivity at low lux levels.

In addition, the ISL29009 has an EN pin that can be used for

a polling scheme extending portables’ battery life.

The ISL29009 is housed in an ultra compact 2mmx2.1mm

ODFN plastic case surface mount package. Operation is

rated from -40°C to +85°C.
