NEW!Ultrasensitive Magnetometer Evaluation Board
 
ALT021-10E Evaluation Board
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.

EVB transfer function

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

This video showcases the remarkable sensitivity of the ALT021-10E using the new evaluation board:

7 kV Isolators
 
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!125 °C
Isolated RS-485 Transceivers
 
T-Series Logo  
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:

An eight-bit A-to-D convertor measures the voltage, the data are isolated by a pair of four-channel isolators, then converted back to analog by a D-to-A convertor.

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:
