Low Profile Six Degree of Freedom Inertial Sensor Data Sheet ADIS16334 FEATURES GENERAL DESCRIPTION Triaxis digital gyroscope with digital range scaling
The ADIS16334 iSensor® is a complete inertial system that includes
±75°/sec, ±150°/sec, ±300°/sec settings
a triaxis gyroscope and triaxis accelerometer. Each sensor in the
Tight orthogonal alignment: <0.05°
ADIS16334 combines industry-leading iMEMS® technology
Triaxis digital accelerometer: ±5 g
with signal conditioning that optimizes dynamic performance.
Wide sensor bandwidth: 330 Hz
The factory calibration characterizes each sensor for sensitivity,
Autonomous operation and data collection
bias, alignment, and linear acceleration (gyro bias). As a result,
No external configuration commands required
each sensor has its own dynamic compensation formulas that
Start-up time: 180 ms
provide accurate sensor measurements over a temperature
Factory-calibrated sensitivity, bias, and axial alignment
range of −20°C to +70°C.
Calibration temperature range: −20°C to +70°C
The ADIS16334 provides a simple, cost-effective method for
SPI-compatible serial interface
integrating accurate, multiaxis, inertial sensing into industrial
