|
The new ALT021-10E-EVB02
is a small printed circuit board
assembly that allows you to evaluate NVE’s ultrasensitive ALT021-10E
TMR sensor magnetometer with a 5x amplifier.
Key eval board features include:
• Remarkable 2.5 V/V/mT typ. sensitivity
• Miniature 13 x 8 mm PCB size
• Bipolar magnetic response
• Single-ended output
• 0.9 to 7 V supply voltage
• 1.1 to 1.6 mA current draw

Best-in-Class Isolation
Voltage
IL700V-Series isolators have been upgraded to a remarkable 7 kVrms (9.9 kVpk),
making them the toughest isolators available.
We demonstrate that the parts withstand 7 kV for one minute, and unlike most tests,
we show the isolators keep operating throughout the test:
A Full Range of Configurations
All three standard four-channel IL700V-Series isolator configurations are in stock
for immediate delivery, with two- and five-channel versions coming soon:

New “T-Series” isolated
transceiver versions are rated to 125 °C. These devices provide exceptional
performance combined with unsurpassed ruggedness
The World’s Fastest Isolated Transceivers
IL3085-family isolators are rated at 4 Mbps, which is ideal for various general
applications. IL3685 isolators boast a best-in-class 40 Mbps data rate with
corresponding fastest available propagation delay and pulse skew.

Extreme Environments
The new IL3085TE and IL3685TE isolators are designed for extreme environments
with their extended temperature range and 15 kV bus ESD. The IL3685 also
has thermal shutdown protection to allow reliable high-speed, high-temperature
operation.
Gold-Standard Certifications
NVE isolators are certified to the rigorous new IEC 60747-17 (VDE 0884-17):2021-10
standard. Many other isolators claim conformance to obsolete editions.
Demonstration
We demonstrated the ruggedness of the IL3685TE with a toaster oven torture test.
These parts keep working when conventional parts are “toast”:

Isolated
Parallel A-to-D-to-A Conversion
NVE isolators are ideal for
isolating parallel data convertors such as ADCs and DACs. Isolation prevents ground
loops and enhances safety.
This reference design is for high-speed, asynchronous analog-to-analog isolation
with just a few chips, no microprocessor, and no software:
Isolated Parallel A-to-D-to-A Conversion.

The circuit uses a simple astable oscillator as a sampling clock, with an ADC
sampling rate more than 100 kS/s.
Since the IL715
isolators have rail-to-rail outputs, an inexpensive R/2R network can replace the
DAC in some applications.
This video shows the circuit and some variations in operation:
