Two miniature surface-mount-technology (SMT ) digital color sensors are designed for use in small consumer and portable-electronic applications. The ADJD-S311, that measures 2.2 × 2.2 × 0.76 mm, is a CMOS IC with integrated RGB filters that targets designers of portable devices that require high integration, small size, and low-power consumption. The ADJD-S371-QR999 measures 3.9× 4.5 × 1.8 mm and is said to be the first and smallest reflective digital color-sensing module that incorporates a white LED and digital color sensor. Both digital color sensors are four-channel red, green, blue (RGB), and clear digital color sensors with a 10-bit resolution.

Both color sensors provide all necessary circuitry to directly interface with a microprocessor using a conventional two-wire serial interface. Moreover, the sensors operate from a 2.5-V supply for low-power consumption from portable devices. A development kit, the HDJD-JD07, comes complete with all the tools and software that lets designers with little to no prior experience using color sensors develop color-sensing and measurement applications. Sensor operating temperature is from 0 to 70°C. And the package is lead-free.
