NEW! IL3022E Low-Cost
RS-422 Transceiver
IL3022 Block DiagramThe IL3022E is a cost-effective galvanically isolated, high-speed, full-duplex bus transceiver.

The new device uses NVE’s patented IsoLoop spintronic Giant Magnetoresistance (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life, and the True 8™ wide-body package provides true 8 mm creepage in accordance with ISO60601. Features include:
  • 4 Mbps data rate
  • Full duplex
  • 600 VRMS working voltage per VDE V 0884-10
  • 2500 VRMS isolation voltage
  • 44000 year barrier life
  • Low EMC footprint
  • Thermal shutdown protection
  • 0.3" True 8™ mm 16-pin SOIC package
There are now nine members of NVE’s isolated digital transceiver family in various packages, including the unique QSOP and narrow-body packages, the industry’s smallest isolated transceivers:

Isolator distributor HY LINE Power Components is exhibiting at the Embedded World exhibition, March 14 to 16 in Nuremberg, Germany in Hall 1 / Stand 170. IsoLoop Isolated Bus Transceivers are popular for embedded applications.
Pi Day Applications
In honor of Pi Day, 3/14, we’re focussing on applications that make good use of pi this month.

Ampere’s Law
Ampere's law can be used to calculate the magnetic field for a sensor used as a current sensor over a circuit board trace. The law typically simplifies to:

This new video demonstrates Ampere’s law using a unique bipolar analog magnetic sensor. We even use a current-mode power supply that outputs ±pi amps for easy figuring.
JavaScript Angle Calculation
for AAT Angle Sensors

This equation calculates the angle, in degrees, indicated by an AAT sensor’s two outputs:
JavaScript calculation
Since the arctangent is a ratio calculation, the formula cancels power supply variations. And unlike the one-variable arctan function, the two-variable “atan2” provides a full 360-degree angle range.

This new video shows the complete, simple AAT graphical user interface:
