The ADXRS450 is an angular rate sensor (gyroscope) intended for industrial, medical, instrumentation, stabilization, and other high performance applications. An advanced, differential, quad sensor design rejects the influence of linear acceleration, enabling the ADXRS450 to operate in exceedingly harsh environments where shock and vibration are present.The ADXRS450 uses an internal, continuous self-test architecture. The integrity of the electromechanical system is checked by applying a high frequency electrostatic force to the sense structure to generate a rate signal that can be differentiated from the baseband rate data and internally analyzed.The ADXRS450 is capable of sensing angular rate of up to ±300°/sec. Angular rate data is presented as a 16-bit word, as part of a 32-bit SPI message.The ADXRS450 is available in a cavity plastic 16-lead SOIC (SOIC_CAV) and an SMT-compatible vertical mount package (LCC_V), and is capable of operating across both a wide voltage range (3.3 V to 5 V) and temperature range (−40°C to +105°C).APPLICATIONSRotation sensing medical applicationsRotation sensing industrial and instrumentationHigh performance platform stabilization

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
