GENERAL DESCRIPTION
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 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.
