San Jose, Calif. Avago Technologies has announced the availability of two miniature surface-mount digital color sensors for use in small consumer and portable electronic applications, which it says are the smallest in the industry. Some of the target applications for the RGB color sensors include mobile phones, personal data assistants (PDAs), MP3 players, handheld games, and portable color detection and measurement devices.
The ADJD-S311 with dimensions of 2.2 x 2.2 x 0.76 mm is a CMOS IC with integrated RGB filters. This color sensor targets portable devices that require higher integration, smaller size and low-power consumption. The ADJD-S371-QR999 with dimensions of 3.9 x 4.5 x 1.8 mm is said to be not only the smallest but also the industry's first reflective digital color sensing module that incorporates a white LED and digital color sensor.
The ADJD-311 and ADJD-S371 digital color sensors are four-channel red, green and blue (RGB) and clear digital color sensors with 10-bit resolution, which provide designers with easy integration, installation, and design flexibility particularly for those designs where board space is constrained, said Avago. Both the ADJD-S311 and ADJD-S371 digital color sensors provide all the necessary circuitry to directly interface with a microprocessor using a conventional two-wire serial interface. These sensors operate from a 2.5-V supply voltage, providing significantly lower power consumption for portable devices.
The small form factor ADJD-S311 four-channel digital sensor comes in a chip-scale package (CSP) that enables designers to accommodate more enhancements in the same amount of board space and can lead to further reductions in design and manufacturing costs, said Avago. The ADJD-S371 is a reflective sensor module that incorporates the ADJD-S311 and a white chipLED soldered to the printed-circuit-board (PCB) with a separator.
To make it easy for designers to evaluate and design-in these miniature color sensors, Avago also offers a complete "plug and play" development kit that interfaces to a personal computer through a USB port. The HDJD-JD07 development kit comes complete with all the required tools and software.
Pricing: The ADJD-S311 and ADJD-S371 (lead free) color sensors are priced starting at $1.50 and $2.50 respectively in quantities of 10,000. The HDJD-JD07 development kits are priced at $515 each.
