Main Title

6 axis MEMS motion and pressure sensor combo

Mixed Media

The 7-Axis ICM-20789 is an integrated 6-axis inertial device that combines a 3-axis gyroscope, 3-axis accelerometer, and an ultra-low noise MEMS capacitive barometric pressure sensor in a 24-pin LGA package. This unique 7-Axis device offers performance of discrete components in a single small footprint for tracking rotational and linear motion as well as pressure differences with an accuracy of ±1 Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm.

The pressure sensor’s MEMS capacitive architecture provides the industry’s lowest noise at the lowest power, high sensor throughput, and temperature coefficient offset of ±0.5 Pa/°C. The pressure sensor’s combination of high accuracy elevation measurements, low power, and temperature stability complemented by the motion tracking 6-axis inertial sensor in a small footprint, make it ideal for a wide range of motion tracking applications.

The 7-Axis ICM-20789 provides an easy upgrade path to build on the time-tested performance of TDK-InvenSense’s 6-axis inertial sensors by adding a ultra-low noise and temperature stable MEMS capacitive barometric pressure sensor.
