Low Profile Six Degree of Freedom Inertial Sensor ADIS16334 Data Sheet FEATURES GENERAL DESCRIPTION Triaxis digital gyroscope with digital range scaling ±75°/sec, ±150°/sec, ±300°/sec settings Tight orthogonal alignment: <0.05° Triaxis digital accelerometer: ±5 g Wide sensor bandwidth: 330 Hz Autonomous operation and data collection No external configuration commands required Start-up time: 180 ms Factory-calibrated sensitivity, bias, and axial alignment Calibration temperature range: −20°C to +70°C SPI-compatible serial interface Embedded temperature sensor Programmable operation and control Automatic and manual bias correction controls Bartlett window FIR filter length, number of taps Digital I/O: data ready, alarm indicator, general-purpose Alarms for condition monitoring Enable external sample clock input: up to 1.2 kHz Single-command self-test Single-supply operation: 4.75 V to 5.25 V 2000 g shock survivability 24 mm × 33 mm × 11 mm module with connector interface Operating temperature range: −40°C to +105°C The ADIS16334 iSensor® is a complete inertial system that includes a triaxis gyroscope and triaxis accelerometer. Each sensor in the ADIS16334 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements over a temperature range of −20°C to +70°C. The ADIS16334 provides a simple, cost-effective method for integrating accurate, multiaxis, inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. An improved SPI interface and register structure provide faster data collection and configuration control. This compact module is approximately 24 mm × 33 mm × 11 mm and provides a compact connector interface.
