electronica 2018: Get smart, Get small, Get integrated
I thought I heard about 100 different languages spoken as I crisscrossed 17 halls over four days in Munich at electronica 2018 with an average of eight miles a day of walking. I was wrong. It was closer to 180 languages. Tens of thousands of attendees were laser-focused on simplifying design and integrating devices and […]
Low-power single-chip temperature sensor performs like RTDs
Texas =Instruments has introduced a new temperature sensor family that offers ±0.1°C accuracy across a wide temperature range and helps simplify system design for industrial and medical applications. The TMP117 is the first single-chip temperature sensor to offer similar performance to platinum resistance temperature detectors (RTDs) while significantly reducing design complexity and power consumption, and […]
How telematics is evolving with the connected car
The embedded systems that control vehicle tracking grow more sophisticated by the day. Hope Bovenzi, Texas Instruments Inc. THE phrase “car of the future” often invokes thoughts about autonomous driving. But it is fair to also consider what it will be like as a passenger once our driving habits change. With free hands and relaxed […]
Grid links get more compact thanks to gallium nitride
Serkan Dusmez from Texas Instruments recently recorded a short video with us on a gallium-nitride based grid link. It is a three-phase, three level bidirectional grid tight inverter developed jointly by Texas Instruments and Siemens. It includes 600-V GaN TI drivers that incorporate smart features like over voltage protection and over temperature protection in a […]
TI SiC MOSFET gate drivers make for smaller inverters
Nagarajan Sridhar from Texas Instruments recently filmed a video with us covering a demo of a solar panel inverter that uses Texas Instruments silicon carbide MOSFET gate drivers. He points out that the switching frequency of silicon carbide far exceeds the capability of that available through silicon IGBTs or MOSFETs. The demo circuit is a […]
Controllers for micromirror imaging deliver micron-to-sub-millimeter accuracy for 3D printers and portable 3D scanners
Texas Instruments today announced new DLP Pico controllers that deliver advanced light control capabilities in smaller form factors for mass-market 3D scanners and 3D printers. DLPC347x controllers offer the micron-to-sub-millimeter resolution typically found in high-performance, industrial-grade applications in a smaller form factor for desktop 3D printers and portable 3D scanners. Developers can pair the new […]
High-voltage amplifiers optimized for error-sensitive apps
Texas Instruments (TI) today introduced three new amplifiers with a unique combination of high speed and high precision, allowing designers to create more accurate circuits for error-sensitive applications. The new devices support more precise measurement and faster processing of a wide variety of input signals in test and measurement, medical, and data-acquisition systems. To learn […]
Wide-VIN synchronous DC/DC buck regulators come in ultra-small QFN packaging
Texas Instruments today introduced two wide-VIN synchronous SIMPLE SWITCHER DC/DC buck regulators in ultra-small HotRod quad flat no-lead (QFN) packaging. The highly integrated 3-A LMR33630 and 2-A LMR33620 step-down voltage converters feature the industry’s best full load efficiency – 92 percent – for rugged and reliable industrial power supplies with switching frequencies up to 2.1 MHz. Used in conjunction with TI’s […]
Teardown: Inside the Neurometrix Quell TENS device
A TENS device for transcutaneous electrical nerve stimulation wraps around the upper calf much like a wristwatch wraps around the wrist. Here are some of its operational secrets. A medical device called a Quell performs what’s called transcutaneous electrical nerve stimulation on the lower leg. This technique is said to relieve diabetic pain. None of […]
