IL3022E
Low-Cost
RS-422 Transceiver |
|
|
 The
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:

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.

Angle Calculation
for AAT Angle Sensors
This equation calculates the angle, in degrees, indicated by an AAT sensor’s
two outputs:
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:
You can e-mail us for the JavaScript
code, and you can order AAT angle sensor Evaluation
Kits from our online store. |
