Vishay Intertechnology Launches Integrated RGBC-IR Color Sensors With I²C Interface in Low Profile Packages
January 27 2020 - 11:00AM
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.
