The OPT4048 is a single-chip high resolution color sensor, capable of measuring four channels each with specific engineered spectral responses. Three of the four channels closely match the CIE tristimulus spectra with the fourth channel having a wide band spectral response. With measurements from these channels, important characteristics of the lighting environment can be extracted like (i) light intensity (lux), (ii) color in CIE XY, LUV coordinates and (iii) Correlated Color Temperature. The OPT4048 is available in a small SOT-5X3 package.

The OPT4048 has a selectable addressing scheme to enable up to 4 devices on a shared I2C bus. The spectral response of the channels have been specially tuned to closely mimic the CIE tristimulus spectra to get the most accurate color detection, with strong rejection for wavelengths away from their respective peaks, especially the NIR (850 nm & 940 nm) region. The filters use an advanced filter technology which provides excellent filter performance even at higher angles of light incidence. This device, with high accuracy color sensing capability, enables several applications requiring precise sensing of ambient light color and color temperature.

The engineered optical filter on OPT4048 provides strong infrared rejection, which aids in maintaining high accuracy, despite placing the sensor under dark glass, which is common requirement from industrial design of end products due to aesthetics.

The OPT4048 is designed for systems that require light level detection to enhance user experience by providing information not only about the intensity, but the color of the illumination.

The OPT4048 device can be configured to operate with light conversion times all the way from 600 µs to 800 ms in 12 steps per channel, providing system flexibility based on application need. Conversion time includes the light integration time and ADC conversion time. Resolution of the measurement is determined by a combination of light intensity and the integration time, effectively bringing in capability to measure down to 2.15 mlux.

The digital operation is flexible for system integration. Measurements can be either continuous or triggered in one shots with register writes or hardware pin. The device features a threshold detection logic, which allows the processor to sleep while the sensor watches for appropriate wake-up event to report via the interrupt pin.

Digital output, representing the light level is reported over an I2C and SMBus compatible, two-wire serial interface.

The low power consumption and low power-supply voltage capability of the OPT4048 helps enhance the battery life of battery-powered systems.
