Precision, Miniature MEMS IMU Data Sheet ADIS16505 FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope The ADIS16505 is a precision, miniature microelectromechanical 125/sec, 500/sec, 2000/sec dynamic range models system (MEMS) inertial measurement unit (IMU) that includes 2.3/hr in-run bias stability (ADIS16505-1) a triaxial gyroscope and a triaxial accelerometer. Each inertial 0.13/hr angular random walk, x-axis and y-axis, 1 sensor in the ADIS16505 combines with signal conditioning (ADIS16505-1) that optimizes dynamic performance. The factory calibration 0.25 axis to axis misalignment error characterizes each sensor for sensitivity, bias, alignment, Triaxial, digital accelerometer, 78.4 m/sec dynamic range linear acceleration (gyroscope bias), and point of percussion 26.5 m/sec in-run bias stability (x-axis and y-axis) (accelerometer location). As a result, each sensor has dynamic Triaxial, delta angle and delta velocity outputs compensation formulas that provide accurate sensor Factory calibrated sensitivity, bias, and axial alignment measurements over a broad set of conditions. Calibration temperature range: 40C to +85C The ADIS16505 provides a simplified, cost effective method for SPI compatible data communications integrating accurate, multiaxis inertial sensing into industrial Programmable operation and control systems, especially when compared with the complexity and Automatic and manual bias correction controls investment associated with discrete designs. All necessary motion Data ready indicator for synchronous data acquisition testing and calibration are part of the production process at the External sync modes: direct, scaled, and output factory, greatly reducing system integration time. Tight orthogonal On demand self-test of inertial sensors alignment simplifies inertial frame alignment in navigation On demand self-test of flash memory systems. The serial peripheral interface (SPI) and register Single-supply operation (VDD): 3.0 V to 3.6 V structure provide a simple interface for data collection and 2 14,700 m/sec mechanical shock survivability configuration control. Operating temperature range: 40C to +105C The ADIS16505 is available in a 100-ball, ball grid array (BGA) APPLICATIONS package that is approximately 15 mm 15 mm 5 mm.
