Precision, Miniature MEMs IMU Preliminary Technical Data ADIS16465 FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope
The ADIS16465 is a precision, miniature MEMS inertial measure-
±125°/sec, ±500°/sec, ±2000°/sec range models
ment unit (IMU) that includes a triaxial gyroscope and a triaxial
2°/hr in-run bias stability (ADIS16465-1)
accelerometer. Each inertial sensor in the ADIS16465 combines
0.15°/√hr angle random walk (ADIS16465-1 and
with signal conditioning that optimizes dynamic performance.

The factory calibration characterizes each sensor for sensitivity,
±0.1° axis to axis misalignment error
bias, alignment, linear acceleration (gyroscope bias), and point
Triaxial, digital accelerometer, ±8 g
of percussion (accelerometer location). As a result, each sensor

has dynamic compensation formulas that provide accurate
Triaxial, delta angle and delta velocity outputs
sensor measurements over a broad set of conditions.
