The SM223-10E Smart Magnetometer combines a Tunneling Magnetoresistance (TMR) sensor element with
sophisticated digital signal processing for a unique combination of speed and precision. An I2C interface provides data as well as an external programming interface, and allows setting a versatile digital threshold output.
Unlike awkward, old-fashioned Hall-effect sensors, TMR is sensitive in-plane for
optimal current sensing and easy mechanical interfaces. Key features include:
0 to 1.5 mT linear range
Can detect magnets more than 150 mm away
Simple I2C interface
Programmable digital threshold output
2% of full-scale accuracy for 0 to 125°C
Fast 10000 sample-per-second update rate
Factory calibrated
Programmable offset and gain compensation
-40°C to +125°C operating range
Ultraminiature 2.5 x 2.5 mm DFN6 package
The AG919-06 is a 2 x 0.25 inch (50 x 6 mm) PCB designed to be used with MSOP8 sensors (-00E package; order sensors separately). The MSOP8 is rotated 90 degrees compared to the AG918-06.
The AG960-07E provides easy connections to an SM324-10E Precision TMR Smart Magnetometer. In addition to the sensor, the board has a recommended bypass capacitor and a six-pin header connected to each of the sensor I/O pads.
The board is approximately 0.5 by 0.6 inches (12 x 15 mm).
This board demonstrates an isolated, high-efficiency synchronous buck converter switch-mode
power supply (SMPS) using the world’s smallest isolators, NVE IsoLoop® MSOP Isolators.
The output is 3.3V at 750 mA.
The board has three channels of isolation to ensure the output is electrically isolated from the
input. A two-channel MSOP-8 isolator isolates synchronous rectification and a single-channel,
failsafe, MSOP-8 isolator isolates output-voltage feedback. MSOP isolators minimize board area.
Despite the compact components, the board has 1.2 kV isolation and maintains 3 mm creepage.
