The ADIS16477 is a precision, miniature MEMS inertial measurement unit (IMU) that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16477 combines with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). As a result, each sensor has dynamic compensation formulas that provide accurate sensor measurements over a broad set of conditions.The ADIS16477 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. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.The ADIS16477 is available in a 44-ball, ball grid array (BGA) package that is approximately 11 mm ? 15 mm ? 11 mm.Applications Navigation, stabilization, and instrumentation Unmanned and autonomous vehicles Smart agriculture/construction machinery Factory/industrial automation, robotics Virtual/augmented reality Internet of Moving Things

The ADXL343 is a versatile 3-axis, digital-output, low?g MEMS accelerometer. Selectable measurement range and bandwidth, and configurable, built-in motion detection make it suitable for sensing acceleration in a wide variety of applications. Robustness to 10,000 g?of shock and a wide temperature range (?40?C to +85?C) enable use of the accelerometer even in harsh environments.The ADXL343 measures acceleration with high resolution (13-bit) measurement at up to ?16g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. The ADXL343 can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0?.Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins.An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption.The ADXL343 is supplied in a small, thin, 3 mm ? 5 mm ? 1 mm, 14-terminal, plastic package.APPLICATIONS Handsets Gaming and pointing devices Hard disk drive (HDD) protection

The EVAL-ADXL345Z is a simple breakout board that enables easy connection of an ADXL345 into an existing system. The ADXL345 is a digital-output, 3-axis accelerometer whose low power consumption and built-in features make it ideal for use in a wide variety of applications. Due to its small size, the EVAL-ADXL345Z has minimal effect on performance of the system and of the accelerometer, and thus it is ideal for evaluation of the ADXL345 in an existing system. Note that the ADXL345 must be communicated with digitally via SPI or I2C. No processor is included with the EVAL-ADXL345Z; firmware must be supplied externally by the user. For evaluation boards that include a processor, please see the EVAL-ADXL345Z-M and the ADXL345Z-DB.
