MEMS accelerometers and iSensor MEMS accelerometer subsystems from Analog Devices to accurately detect and measure acceleration, tilt, shock and vibration in performance-driven applications. Signal conditioning technology is integrated into every MEMS accelerometer, gyroscope, inertial measurement unit (IMU) from Analog Devices (ADI).
Single and multi-axis Accelerometer ICs, suitable for a wide range of applications where acceleration needs to be measured or monitored. Use to measure both static acceleration due to gravity and dynamic acceleration resulting from motion, shock, or vibration.
