The AXO®314 is a high-precision digital MEMS accelerometer with a closed-loop architecture, designed to provide excellent stability and repeatability in environments with significant shock and vibration, as well as in other high-dynamics applications. With a ±14 g input range and a bias instability of 4 µg, it is ideal for incorporation into IMUs, INS and other navigation and positioning solutions for drones and robotics.
The SWaP-optimized accelerometer has been factory-calibrated over the entire operating temperature range, is enclosed within a miniature hermetic SMD package, and includes built-in self-test capabilities for initial verification of the sensor’s integrity and continuous in-operation functionality. With a 24-bit digital SPI interface, it can be easily integrated into a wide range of designs.
