IL3x85 isolated
RS-485 transceivers.
|
Award-winning IsoLoop isolated transceivers have always been the best RS-485, RS-422, and PROFIBUS solution. Now they are even more cost-effectiveas low as $2.60 each in 1,000-piece quantities (IL3122 and IL3185). Parts are in stock now and available for immediate delivery.
Key IL3000 features include:
|
Unique 0.15" SOIC
|
• Integrated Transceivers and Isolation
• 0.15" and 0.3"-Wide 16-pin SOIC
• 3 V or 5 V Power Supply
• Digital and Passive Input Versions
• PROFIBUS Version (IL3685)
• Up to 40 Mbps (IL35xx)

24 Volt Current Sensor
Maximum bridge input voltage for the new AAV003-10E GMR current sensor is now specified at 24 V rather than 12 V. The higher range is compatible with PLCs, and provides a remarkable typical sensitivity of 2 mV/mA with no amplification from -80 mA to +80 mA.
In addition to the higher bridge voltage specification, the parts now have an isolation voltage specification of 240 Vrms.

AAV003-10E Current Sensor
|
|
AAV003-10E current sensors are targeted at circuit board current sensing for process control and instrumentation. High sensitivity makes them ideal for 4-20 ma current loop detection.
The parts come in an ultraminiature 2.5 mm by 2.5 mm six-pin TDFN package.

Single-Chip
RS-485 Isolated Transceivers
By Sandy Templeton
Director, Isolator Product Development and Applications
NVEs single-chip isolated RS-485 transceivers dramatically reduce chip count compared to conventional isolation methods. As the circuit above shows, termination resistors (Rt) can be added to maximize speed and transmission
length by reducing reflections. Fail-safe resistors (Rfs) guarantee a known bus state when no transceivers are active.
For more information on how isolated transceivers can dramatically reduce chip count, see Application Bulletin No. 5 (.pdf).
For practical tips for making RS-485 systems work, see Application Bulletin No. 6 (.pdf).
The NVE Website has a number of other isolator illustrative applications. New applications are always being added.
