Norwood, MA (11/08/2011) - Analog Devices, Inc. (ADI) released for general availability today the third generation iSensor® MEMS IMU (inertial measurement unit). The ADIS16488 is a tactical grade 10-degree-of-freedom (DoF) sensor and integrates a tri-axis gyroscope, tri-axis accelerometer, tri-axis magnetometer and a pressure sensor into a single package. This new MEMS IMU provides the most stable and complete integrated sensor suite available, supporting mission critical requirements in high-performance navigation and stabilization applications. Beyond the important tactical grade (below 10°/hr) bias stability, the ADIS16488 outperforms all other contemporary gyro/IMU offerings on the often more critical specifications of g-effect, temperature coefficient, and bandwidth by up to 100X. Further, the new iSensor MEMS IMU even outperforms legacy military grade IMUs on vibration rectification and linearity. Every device undergoes unique and extensive factory calibration, resulting in unparalleled precision in the toughest environments and greatly reduces complexity, time, cost, and design risk relative to typical motion sensor development.

“For industrial, military, and medical equipment designers who require the most accurate detection and control of motion in order to stabilize or navigate their applications, the ADIS16488 tactical grade IMU offers performance levels previously only available to those with unlimited budgets,” said Bob Scannell, iSensor business development manager, MEMS/Sensors Technology Group, Analog Devices. “With equal or better performance to legacy high-end IMUs on key measures such as bias stability and angular random walk, the ADIS16488 provides better performance on the often more critical parameters of vibration-rectification, linearity, and bandwidth while consuming one-quarter the power, and at one-tenth the cost.”

More About the ADIS16488 iSensor 10-DoF MEMS IMU

The ADIS16488 iSensor 10-DoF MEMS IMU is a complete inertial measurement system that combines ADI’s high performance iMEMS® technology and sensor-signal processing expertise to optimize the IMU’s 10-DoF dynamic performance. Operation is fully autonomous, including all embedded compensations, with valid data available from the SPI interface 500 ms after applying power. With all calibration done at the factory, and with an ADI Blackfin® processor-powered configurable interface for tuning embedded filtering and other diagnostics, a major source of design integration time and risk is virtually eliminated.
