±300°/sec High Vibration Immunity Digital Gyro
The ADXRS450 uses an internal, continuous self-test archi-tecture. 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).

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADXRS450 is available in two packages: an SOIC package for yaw-axis rate sensing, and a vertical-mount package (VMP) for pitch- or roll-axis sensing. In applications requiring multi-axis sensing, the innovative VMP greatly simplifies assembly by eliminating the need for additional boards mounted at 90°. Breakout boards are available for the ADXRS450 in both packages, as listed in the Ordering Guide below.
Due to its small size and stiff PCB, the EVAL-ADXRS450Z has minimal effect on performance of the system and of the gyroscope, and thus it is ideal for evaluation of the ADXRS450 in an existing system. Note that the ADXRS450 requires digital communication via SPI. No processor is included with the EVAL-ADXRS450Z; firmware must be supplied externally by the user. For an evaluation system that includes a processor, please see the EVAL-ADXRS450Z-M.
The ISEB is an universal main board and is intended to be used with various satellites of Analog Devices inertial sensors, including analog and digital accelerometers, as well as gyroscopes. The different products are evaluated by means of separate GUIs that are customized for performance and characterization measurements relevant to the inertial sensor being evaluated.
The EVAL-ADxZ-M system contains the ISEB and the EVAL-ADxZ-S satellite. Also included is an USB A to Mini-B cable to connect the ISEB to a PC and an 18-inch, 20-pin ribbon cable to connect the ISEB to the satellite.
