Low-Power Isolated
RS-485 Transceiver |
|
|
 With
a typical total quiescent current of just 2.4 mA at 5 volts, the new
IL2985 draws less than one-third the supply current of our standard products,
which are already fairly low power.
Even with the low power, there’s no compromise in performance:
• 4 Mbps data rate
• 2500 VRMS isolation voltage
• 44000 year barrier life
• Low EMC footprint
• Thermal shutdown protection
The new device uses NVE’s patented low-power spintronic Tunneling Magnetoresistance
(TMR) technology. A unique ceramic/polymer composite barrier provides excellent
isolation and virtually unlimited barrier life.
There are now eleven members of NVE’s best-in-class isolated digital transceiver
family:

Low-Power
Isolated Transceiver Demonstration
We went into the lab to demonstrate the best-in-class efficiency of the new IL2985
isolated transceiver:
Demonstrating the low-power IL2985 isolated transceiver.
The lab results confirmed that the new NVE part was much faster and lower power
than any alternatives.

|
Sensor+Test is billed
as the leading forum for sensors, measuring, and testing technologies worldwide.
NVE had a bumper crop of new sensors since last year’s show, including:
• The world’s smallest analog sensor—the
AAL004-10E.
• The AAT009-10E
ridiculously low-power angle sensor.
• The AAT006-10E
low-field angle sensor.
• The ADT002-10E
rotation quadrant sensor.
• Several new sensor
evaluation kits, including AG040B
battery-powered nanopower sensor demo boards for less than $20. |
