Compact, Precision Ten Degrees of Freedom Inertial Sensor Data Sheet ADIS16448 FEATURES GENERAL DESCRIPTION Triaxial digital gyroscope with digital range scaling The ADIS16448 iSensor device is a complete inertial system 250/sec, 500/sec, 1000/sec settings that includes a triaxial gyroscope, a triaxial accelerometer, a Axis-to-axis alignment, <0.05 triaxial magnetometer, and pressure sensors. Each sensor in Triaxial digital accelerometer, 18 g minimum the ADIS16448 combines industry-leading iMEMS technology Triaxial digital magnetometer, 1.9 gauss minimum with signal conditioning that optimizes dynamic performance. Digital barometer, 10 mbar to 1200 mbar The factory calibration characterizes each sensor for sensitivity, Calibrated pressure range: 300 mbar to 1100 mbar bias, and alignment. As a result, each sensor has its own dynamic Autonomous operation and data collection compensation formulas that provide accurate sensor No external configuration commands required measurements. 205 ms start-up time The ADIS16448 provides a simple, cost-effective method for Factory calibrated sensitivity, bias, and axial alignment integrating accurate, multiaxis inertial sensing into industrial Calibration temperature range: 40C to +85C systems, especially when compared with the complexity and SPI-compatible serial interface investment associated with discrete designs. All necessary motion Burst mode read sequence with optional CRC-16 testing and calibration are part of the production process at the Embedded temperature sensor factory, greatly reducing system integration time. Tight orthogonal Programmable operation and control alignment simplifies inertial frame alignment in navigation systems. Automatic and manual bias correction controls The SPI and register structures provide a simple interface for Bartlett window FIR length, number of taps data collection and configuration control. Digital I/O: data ready, alarm indicator, general-purpose The ADIS16448 has a compatible pinout for systems that currently Alarms for condition monitoring use other Analog Devices, Inc., IMU products, such as Enable external sample clock input up to 1.1 kHz ADIS16334 or ADIS16485. The ADIS16448 is packaged in a Single command self test module that is approximately 24.1 mm 37.7 mm 10.8 mm Single-supply operation: 3.15 V to 3.45 V and has a standard connector interface. 2000 g shock survivability Operating temperature range: 40C to +105C APPLICATIONS Platform stabilization and control Navigation Robotics FUNCTIONAL BLOCK DIAGRAM DIO1 DIO2 DIO3 DIO4/CLKIN RST VDD POWER SELF TEST I/O ALARMS GND MANAGEMENT TRIAXIAL GYRO OUTPUT CS TRIAXIAL DATA ACCEL REGISTERS CALIBRATION SCLK CONTROLLLER AND TRIAXIAL SPI FILTERS MAGN DIN USER CONTROL PRESSURE DOUT REGISTERS CLOCK TEMP VDD ADIS16448 Figure 1.
