Smart
TMR Angle Sensor |
|
|
The ASR002-10E is the
world’ first Smart TMR Angle Sensor, combining a Tunneling Magnetoresistance
(TMR) sensor element with elegant digital signal processing.
A high-speed SPI interface provides access to the sensor data, as well as user-programmable
parameters:
The ASR002-10E provides an extraordinary combination of speed and precision. Key
features include:
• Factory calibrated
• 0.1° resolution
• ±0.2° repeatability
• Robust 60 to 200 Oe magnetic field operating range
• Fast 12.5 kSps sample rate
• Flexible 2.2V to 3.6V supply range
• Low 4 mA typical supply current
• Wide -40°C to +125°C operating range
• Ultraminiature 2.5 x 2.5 x 0.8 mm TDFN package

Year
in Review |

|
new product highlights included:
 |
|
GMR
Smart Magnetometer
The new SM124-10E Smart Magnetometer combines a versatile GMR sensor element with
digital signal processing. Single-byte (eight-bit) digital data provides a slick,
easy-to-use interface, and its unique architecture eliminates the need for any
commands.
It features an I2C interface and a digital output with programmable
thresholds. Unlike awkward, old-fashioned Hall-effect sensors, GMR is sensitive
in-plane for optimal current sensing and easy mechanical interfaces. |
|
 |
|
TMR
Smart Magnetometer Sensor
The new SM324-10E combines an ultra-precise TMR sensor element with sophisticated
three-byte (24-bit) digital signal processing.
Like the GMR version (above), this part has an I2C interface plus a
digital output with programmable thresholds. And like GMR, TMR is sensitive in-plane
for ease of use.

AAL024
Noncontact Current Sensor
The AAL024-10E combines small size, high sensitivity, and cross-axis sensitivity
for an ideal current-over-trace sensor.
It provides 3.6 mV/V/Oe typical magnetic sensitivity over a 1.5 to 10.5 Oe linear
range. It is inherently omnipolar for AC or DC measurements, and comes in an ultraminiature
2.5 mm x 2.5 mm x 0.8 mm TDFN6.

AAL024
Evaluation Board
Four AAL024 sensors
(see above) in four different circuit board configurations. The 2" x
2" board provides isolated AC or DC measurement of currents up to 5 amps.
Sensitivity is as high as to 60 mV/V/A typ, or 300 mV/A with a 5V supply.

40
Mbps QSOP
RS-485 Transceiver
The world’s fastest isolated RS-485 transceivers are now also the world’s
smallest. The new IL3685-1E is an ultrahigh-speed isolated transceiver in NVE’s
ultraminiature, low thermal resistance QSOP-16 package.

Ridiculously Low Power Sensors
We’ve further tightened the already ridiculously low power consumption specifications
of ADL-Series Nanopower Magnetic Switches. Power consumption is as low as 72 nW,
so they will run nearly forever on a single lithium coin cell. ADL sensors are
also NVE’s smallest parts at just 1.1 mm x 1.1 mm x 0.35 mm. |
|
 |
|
ADL021
Nanopower Sensor
Mini Eval Board
The AG040B is a 0.25 x 1.57 inch demo board with the ultralow-power,
ultraminiature ADL021 magnetic switch (see above). Powered by a coin cell (included),
the quiescent power is so low the battery will last indefinitely. An LED indicates
when the sensor is activated; a miniature bar magnet is included.
|
|
|
|
Low-Power
Isolators
With a typical total quiescent current of just 0.3 mA per
channel, the new IL01x-Series low-power isolators draw one-fourth the power of
our flagship products. The new isolators also feature 10 Mbps data rates,
2.5 kV isolation, and 44000-year barrier life.

NVE researchers authored a
paper that will be presented at the Joint MMM-Intermag Conference,
January 14 through January 18, 2019 in Washington, DC. The prestigious
conference is only convened every three years. |
