I'm here with Sandy, in the NVE Applications Center.
Sandy, tell us about NVE's industry-leading IsoLoop "IL700" isolators.
Sure. Here's a single-channel functional diagram.
IL700s are digital-in, digital-out galvanic isolators.
They use spintronic GMR, rather than optical technology.
Key features include:
5- or 3-volt operation;
2,500-volt isolation, which complies with UL1577 and IEC61010.
Parts also feature low EMC footprint and best-in-class speed and distortion,
with many I/O configurations, packages, and variants.
What I/O configurations are there?
Just about all possible one, two, four, and five channel configurations are available.
There are also several variants for particularly demanding needs:
IL200-Series have five channels per package.
"-1" Series are MSOPs and QSOPs— the world's smallest isolators.
"S" stands for speed, at 150 megabits per second,
and lowest pulse-width distortion of 300 picoseconds.
Finally, T-Series IsoLoops have the highest operating temperature of 125C.
What parameters set IL700s apart?
Here are a few:
highest data rate;
lowest distortion as measured by PWD, prop delay, skew, and jitter;
excellent transient immunity;
and wide temperature ranges.
We summarize the advantages with the four "Bs":
Boxes—package options to maximize channel density or creepage distance;
Bits—up to five channels per device;
Baud—highest speed and lowest distortion;
and Bulletproof, including temperature, transients,
and barrier life.
The four "Bs." As you British say, "brilliant." What packages are available?
Several choices.
I mentioned MSOPs and QSOPs for highest channel density.
Eight-pin SOICs and PDIPs for drop-in replacement;
16-pin narrow SOICs, for four or five channels per package,
plus wide SOICs or PDIPs for maximum creepage and clearance.
What are popular applications?
A lot of IL700s replace optocouplers
with higher speed, less distortion, longer life, and higher channel density.
Well, I hate optos...
Join the club. and other popular IL700 applications include:
Serial interfaces;
Isolated SPI;
Isolated A-to-D converters;
and power interfaces.
