3 Description
The OPT3006 is a single-chip lux meter, measuring
the intensity of visible light as seen by the human
eye. The OPT3006 is available in an ultra-small
PicoStar package, so the device fits into tiny spaces.
The precision spectral response of the sensor tightly
matches the photopic response of the human eye.
With strong infrared (IR) rejection, the OPT3006
accurately meters the intensity of light as seen by the
human eye, regardless of the light source. The strong
IR rejection also aids in maintaining high accuracy
when design requires mounting the sensor under
dark glass. The OPT3006, often in conjunction with
backlight ICs or lighting control systems, creates lightbased
experiences for humans, and is an ideal
replacement for photodiodes, photoresistors, or
lower-performing ambient light sensors.
Measurements can be made from 0.01 lux up to 83k
lux without manually selecting full-scale ranges by
using the built-in, full-scale setting feature. This
capability allows light measurement over a 23-bit
effective dynamic range.
The digital operation is flexible for system integration.
Measurements can be either continuous or singleshot.
The control and interrupt system features
autonomous operation, allowing the processor to
sleep while the sensor searches for appropriate
wake-up events to report with the interrupt pin. The
digital output is reported over an I2C- and SMBuscompatible,
two-wire serial interface.
The low power consumption and low power-supply
voltage capability of the OPT3006 enhance the
battery life of battery-powered systems.
