High Performance MEMS Inertial Measurement Unit IMU Sensor
ADIS16488 Replacement
The 16488HA Inertial Measurement Unit (IMU) is a fully integrated inertial sensing system that combines a three-axis gyroscope and a three-axis accelerometer within a compact module. It is designed to accurately measure three-axis angular velocity and linear acceleration of the host platform.
The system performs advanced error compensation, including:
After compensation, the unit outputs high-precision inertial data
via an SPI digital interface, following a standardized communication protocol. This makes the
16488HA IMU highly suitable for embedded applications requiring
reliable and stable motion sensing in dynamic environments.
