Fun Fact
Diamonds Are Forever, and So Are IsoLoops

Diamond
Diamonds are forever, and IsoLoop Isolators come pretty close.

Based on life tests, the calculated FIT is 0.2 failures per billion hours at 55°C, which is an MTBF of 570,000 years.

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:

Eliminating Holiday Jitters

By “Steady” Sandy Templeton
Director, Isolator
Product Development and Applications


Holiday stress can make us jittery, but isolators don't have to.

Audio applications are an example of where minimizing isolator jitter is especially important:

Isolator Jitter
IsoLoop Jitter

Jitter
 

NVE’s IL700 and IL600 Series Isolators have an unmatched 100 ps of jitter, making them ideal for audio circuits or anywhere you want to cure the jitters.

It is extremely desirable to have serial data from a CD or MP3 source isolated from the analog portions of the sound system to eliminate ground loops (speaker hum) and high frequency pickup caused by digital currents flowing in analog current paths:

CD Transport Circuit

Low-Jitter Isolated CD Transport Circuit

Almost any isolator can cure your hum and high frequency current noise problems, but isolator jitter adds phase shift to the PCM data stream, playing havoc with the sonic qualities of the output DAC.

Jitter creates similar problems in precision measurement systems using isolated delta-sigma ADCs. Clock edge placement is directly related to conversion resolution. IsoLoop isolators ensure best-case isolation performance without the tradeoffs caused by the jitters.
