Sensors Emit And Detect Red, Green And Blue Light

Unveiled as the industry's first reflective color sensors, the TRS1722, TRS1755 and TRS1766 are designed to both emit and detect red, green and blue (RGB) colors, respectively. The sensors combine a color LED die and a light-to-voltage converter with a corresponding color filter in a surface-mount package.The output of each device is a voltage that is directly proportional to the color of the reflected light. With the LED drive current being as low as 250 µA (TRS1766 blue LED sensor), these devices are particularly well-suited for use in low-power and battery-operated applications. The reflective sensors also feature eight bits of resolution and can operate on supply voltages from 4.5V to 5.5V and over a temperature range of 0¡C to 70¡C. Price is $1.36 each/1,000.
