Spectral Response: The OPT3006 and Human Eye

OPT3006 D001_SBOS698.gif

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 light-based 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 single-shot. 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 SMBus-compatible, 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.
