RGB Color, Temperature, and Infrared Proximity Sensor

Optical Fusion: Digitize Colors and Detect Proximity at 12µA

Please check latest availability status for a specific part variant.


The MAX44005 integrates 7 sensors in one product: red, green, blue (RGB) sensors; an ambient light (clear) sensor; a temperature sensor; an ambient sensor; and, an infrared proximity sensor with an I2C interface. This highly integrated optical sensor includes a temperature sensor to improve reliability and performance.

The IC computes all the light information with parallel data converters to make simultaneous light measurement in a very short time. The chip consumes only 15µA in RGBC + IR mode and operates at 1.8V supply voltage.

The IC's RGB sensing capability improves the performance of end products by providing robust and precise information for ambient color sensing and color temperature measurement.

The integrated proximity sensor uses a single-pulse LED scheme to achieve very low power consumption. This method also improves sunlight rejection and 50Hz/60Hz noise to deliver reliable proximity measurements. With this technology, the IC is a perfect solution for touch-screen portable devices and presence detection applications.

The on-chip ambient sensor has the ability to make wide dynamic range 0.002~8388.61µW/cm² measurements. The IC's digital computation power provides programmability and flexibility for end-product design. A programmable interrupt pin minimizes the need to poll the device for data, freeing up microcontroller resources, and reducing system software overhead, and ultimately, power consumption. All these features are included in a tiny, 2mm x 2mm x 0.6mm optical package.
