Sensors Converge Recap
North America’s Largest Electronics Event
Thanks to everyone who visited our 2023 Sensors Converge booth in Santa Clara, Calif. We had a good turnout and a successful exhibition. Sensors Converge is billed as North America’s largest electronics event for design engineers. We look forward to following up on your latest and greatest designs.

Hands-on demos are a popular feature at our booths. This year some were from an internal demo design contest. The winner was a “blinky-flashy” demo using several NVE AKT001-14E omnidirectional magnetic sensors.

If you couldn’t make it to the show, here’s a quick look at the demonstrations:

NEW! TMR Guitar Pickup
The World’s Most Sensitive Magnetometers
NVE’s new ALT021-10E is the world’s most sensitive TMR magnetometer, with 500 mV/V/mT sensitivity and field detection as low as one-tenth of a microtesla. These sensitivity figures make the ALT021 competitive with coils, but NVE’s remarkable sensors also offer a flat frequency response from DC to 100 kHz and an ultraminiature 2.5 x 2.5 x 0.8 mm package.

Guitar Pickup Demonstration
We’re always seeking creative new ways to demonstrate the capabilities of our sensors, and we often get feedback from engineers and enthusiasts worldwide. Audio applications are popular requests, so we demonstrated a TMR guitar pickup with ALT021 sensors.

The sensors are so sensitive, that they can detect the metal guitar strings without any external magnets or field biasing. The small remnant magnetic fields in the ferrous strings and the deflection of earth’s magnetic fields are enough to generate several hundred millivolts of signal, which is comparable to conventional single-coil guitar pickups. But unlike bulky guitar pickups, ALT021 sensors can detect DC, have a flat frequency response up to 100 kHz, and are not sensitive to 60 Hz hum interference. These features make ALT021 highly desirable as coil alternates for sensing applications.

We have to admit we prefer the sound of the single-coil pickups for guitar, but stay tuned to follow future TMR guitar pickup design improvements.

16 mm Creepage with NVE Isolators
The World’s Safest, Most Reliable Isolators
NVE’s isolators are known for their unique ceramic/polymer composite isolation barrier, the toughest, most reliable isolation barrier in the world. Offering up to 6000 Vrms isolation voltage and 1200 Vrms working voltage under the IEC 60747-17 (VDE 0884-17):2021-10 “gold standard,” and a virtually unlimited 44000-year barrier life, NVE isolators truly are in a class of their own.

Unlike competing digital isolators, NVE isolators have True 8™ SOIC wide-body packages, the world’s only JEDEC-standard SOIC16 wide-body packages with true 8 millimeter creepage, which is required for medical safety and other equipment under IEC60601.

Increasing Voltages; Increasing Creepage Requirements
The proliferation of increasingly higher voltages in e-mobility and certain medical safety applications is creating more demanding creepage requirements.

Fortunately, NVE’s new IL7000-Series Isolators with Integrated DC-to-DC Converters allow a simple solution for these demanding applications. Two True 8™ millimeter creepage packages in series provide true 16 millimeter creepage.

The illustrative circuit below demonstrates 16 millimeter creepage SPI isolation using NVE’s IL7x17VE and IL717VE in series. The IL7x17VE’s integrated DC-to-DC converter provides a floating supply to power the controller side of the IL717VE:
