AXO®305: High-Performance ±5 g MEMS accelerometer with digital interface

The AXO®305 is a high-performance single-axis closed-loop digital MEMS accelerometer with a ± 5g input range. Featuring an excellent 1-year composite bias repeatability of 1mg, it is ideal for integration into IMUs, INS and MRUs for high-precision navigation and positioning of drones and robotics.

The low-SWaP accelerometer is highly suited as a replacement for bulkier and costlier quartz accelerometers, featuring a 24-bit digital SPI interface for ease of integration and reduction in BOM components.

The hermetically sealed unit also includes a built-in self-test capability that provides initial verification of the sensor’s integrity and continuous in-operation functionality.
