Transistors Gone Wild
Telephone
“Transistors Gone Wild” by The Network is NVE’s current telephone background music, because spintronics are like transistors gone wild.

NVE tries to ensure callers aren’t put on hold, but you can dial (952) 996-1639 option 9 to hear the hold music.

Narrow-Body SOIC-16 Isolators
 
Think Thin!
The world’s densest isolators, IsoLoop “Dash Three” Isolators provide a full line of unique 0.15", narrow-body SOIC-16 isolators—half the size of other isolators.

Thin SOIC Package
Like all IsoLoop Isolators, these products feature minimal signal distortion, wide temperature range, low power consumption, and unlimited life. Narrow-body isolators are available in a variety of input, output, and channel configurations, as well as a full line of isolated RS-485/RS-422/PROFIBUS transceivers.

Key narrow-body isolator features include:

  • 0.15", 16-pin SOIC
  • Passive or digital inputs
  • Three, four, or five channels or isolated RS-422/RS-485
  • IEC 61010-2001 approved
  • 125°C (IL700T-Series)

Nearly 20 Dash Three isolator part types are currently in stock and available for immediate delivery with no minimum order:

Declare Power Supply Independence
 
By Sandy “True Blue” Templeton
Director, Isolator Product Development and Applications

Independence Day is a good time to remember that IsoLoop Isolators can isolate and level-shift between independent supplies.

The figure below shows a common application using an IL717 to isolate and level-shift data from a 5-volt powered sensor and ADC to a 3.3 V logic controller:

Isolated Sensor / ADC Application

Isolating Independent Power Supplies

Isolation keeps the two power supplies independent with separate digital and analog ground current paths. This eliminates ground loops, minimizes noise, and improves measurement accuracy.

IL700/IL200-Series Isolators are available in a variety of configurations with up five channels per device. Versions are available in NVE’s unique, ultra-dense 0.15" narrow-body SOIC package (see featured products above).

So declare your power supply independence with isolation.
