AXO314 high-performance MEMS digital accelerometer

Robust and precise digital MEMS accelerometer

The Tronics AXO314 is a compact high-performance digital MEMS accelerometer with a ±14g input range. The closed-loop architecture offers outstanding linearity and high vibration rejection, making it a cost-effective alternative to bulky tactical-grade quartz accelerometers.

The AXO314 offers a robust and precise acceleration sensing solution with a 1-year composite bias repeatability of 1 mg and bias instability of 4 µg, making it ideal operating in harsh environments.

 

When paired with Tronics’ GYPRO4300 MEMS gyro, which shares the same SMD J-lead package and 24-bit SPI interface, the AXO314 is ideal for integration with tactical-grade IMUs and INS in land, sea, and air applications, as well as GNSS-assisted positioning systems. The AXO314 is not subject to dual-use export control and meets REACH and RoHS standards.

 

Like all MEMS inertial sensors from the Tronics, these accelerometers are factory-calibrated for accuracy across its temperature range, with selectable raw data output for customer-specific compensation strategies.
