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

New Sensors Feature 16-Bit Resolution for Higher Sensitivity and Linearity

MALVERN, Pa. — Jan. 27, 2020 — Vishay Intertechnology, Inc. (NYSE: VSH) today broadens its optoelectronics portfolio with new 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 better linearity and higher sensitivity compared to previous generation devices, as well as new features including an infrared (IR) channel.

The sensors released today 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 various industrial and consumer applications where their excellent temperature compensation capability will keep the sensors’ output stable under changing temperatures.

The sensors’ built-in ambient light photodiode offers extremely 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 easily operated via the simple and power-efficient I²C (SMBus compatible) interface protocol. The devices feature a low operating voltage range of 2.6 V to 3.6 V to help prolong battery life in handheld and portable systems.

Energy-Saving Piezo Haptic Driver is the Touch Sensor's Best Friend

Sponsored by Maxim Integrated

Haptic sensing technology, with its ability to render complex tactile experiences, is becoming popular in portable applications. Excessive power dissipation is a concern with current piezo haptic drivers' implementations. Although the piezoelectric actuator represents a capacitive load, considerable power is dissipated to drive it. This design solution reviews the shortcomings of current piezo haptic driver implementations and introduces a novel, regenerative, boost converter-based implementation that minimizes power dissipation, helping maximize the battery life of portables.
