AXO®305
High Performance ± 5 G MEMS Accelerometer with Digital Interface
Superior bias and scale factor repeatability
AXO®305 is a single-axis, high performance, closedloop digital MEMS accelerometer with ± 5 g input range that offers a digital, cost-effective and lowSWaP alternative to quartz accelerometers.
Its superior 1-year composite bias repeatability of 1 mg makes AXO®305 a perfect candidate for integration into high performance Inertial Measurement Units (IMU), Inertial Navigation Systems (INS) and Motion Reference Units (MRU) for land, railway, marine and subsea applications.
The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of AXO®305 and reduces the BOM. The built-in selftest ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.
