CMS390 (orthogonal)

Industry-leading orthogonal combi-sensor, delivering high-performance bias and noise over temperature.

Our CMS390 combi-sensor is a combined single-axis gyro and dual-axis low-g accelerometer. The unit features user-selectable dynamic range and bandwidth, with a digital SPI output. The CMS390 is mounted on its side (orthogonal), combined with the CMS300 enables all axes to be measured using a single board (PCBA). Measurement range and bandwidth of all three channels can be independently selected by the user.
