Closed-loop Digital SMD MEMS Accelerometers
Miniature, closed-looped digital SMD MEMS accelerometers
with high bias and scale factor repeatability for dynamic applications
Best-in-class performances for demanding applications
AXO® is a unique family of high performance closed-loop digital MEMS accelerometers housed in a SMD package. While open-loop MEMS accelerometers tend to demonstrate poor performances in harsh conditions, the built-in force-rebalance architecture makes our AXO® sensors extremely linear and insensitive to vibrations.
Leveraging best in-class bias repeatability and scale factor repeatability, AXO® is the perfect candidate to sense acceleration in demanding environments.
The unrivalled noise level and excellent bias stability make AXO® an industry-leading sensor solution to build IMU (Inertial Measurement Unit), GNSS-aided positioning, navigation, precision attitude and motion control systems.
Seamless and cost-effective system integration
Our AXO® closed-loop digital MEMS accelerometers sensors feature a 24-bit SPI digital interface and continuous self-test to speed-up their integration compared to conventional analog sensors solutions.
Unlike analog tactical-grade quartz accelerometers that exhibit bulky form factors, our high performance inertial sensors are housed in a hermetic SMD package to reduce the overall SWaP-C (Size, Weight, Power and Cost). In addition, our factory-calibration step removes the need for costly and complex temperature modeling at system-level.
For applications requiring both acceleration and angular rate sensing with high bias stability and high sensitivity constraints, the AXO® closed-loop digital MEMS accelerometers sensors are ideally complemented by our GYPRO® closed-loop gyros that pave the way to a new generation of high performance multi-axis sensors solutions.
