ISL29102 FN6483
Rev.2.00
Nov 17, 2016 Low Power Ambient Light-to-Voltage Nonlinear Converter
The ISL29102 is a low cost, light-to-voltage silicon optical
sensor combining a photodiode array, a nonlinear 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. Features The integrated nonlinear 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 1ВµA op amp gives the ISL29102 an output voltage
driving advantage for heavier loads. Fast response time The ISL29102 is housed in an ultra compact 2mmx2.1mm
ODFN plastic case surface mount package. Operation is rated …
