NVE will exhibit at MD&M
October 10-11 at the Minneapolis Convention Center. Its billed as the
regions most comprehensive medical design and manufacturing event.
See us at booth 3630.
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 Americas 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 couldnt make it to the show, heres a quick look at the demonstrations:

Most Sensitive Magnetometers
NVEs new ALT021-10E
is the worlds 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 NVEs 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
Were 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 earths 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.
Safest, Most Reliable Isolators
NVEs 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
Unlike competing digital isolators, NVE isolators have True 8 SOIC wide-body
packages, the worlds 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, NVEs 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 NVEs IL7x17VE
in series. The IL7x17VEs integrated DC-to-DC converter provides a floating
supply to power the controller side of the IL717VE:
