Vishay Intertechnology Launches Integrated RGBC-IR Color Sensors With I²C Interface in Low Profile Packages

February 6, 2020 Tiera Oliver

Vishay Intertechnology, Inc. introduces RGBC-IR sensors for applications such as automatic white balancing and color cast correction in digital cameras, automatic LCD backlight adjustment, and active monitoring of LED color output for IoT and smart lighting. The new VEML3328 (top-looking) and VEML3328SL (side-looking) sensors offer linearity and sensitivity, as well as new features including an infrared (IR) channel.

The sensors sense red, green, blue, clear, and IR light by incorporating photodiodes, amplifiers, and analog / digital circuits into a single CMOS chip. With the ability to calculate color temperature and sense ambient light, the devices offer a compact solution for adjusting backlighting in consumer electronics and notebook computers. They can also help to differentiate indoor from outdoor lighting environments to ensure that displays maintain consistent true color and ideal brightness levels based on the current environment lighting conditions.

In addition to digital camera and TV applications, the VEML3328 and VEML3328SL will also be used in industrial and consumer applications where their temperature compensation capability will keep the sensors' output stable under changing temperatures.

The sensors' built-in ambient light photodiode offers high sensitivity, allowing the devices to operate in applications with dark lens designs. A programmable analog gain and integration time function, as well as the additional IR channel, allow designers to tailor the VEML3328 and VEML3328SL to their applications.

The sensors' functions are operated via the efficient I²C (SMBus compatible) interface protocol. The devices feature an operating voltage range of 2.6 V to 3.6 V to help prolong battery life in handheld and portable systems.

Samples and production quantities of the VEML3328 and VEML3328SL are available now, with lead times of 16 weeks for larger orders. Pricing for U.S. delivery is $1 per piece in 1000-piece quantities.
