The ADXC1500 is a yaw rate gyroscope and dual-axis accelerometer combined in a single package. It is designed for electronic stability control (ESC) and other high performance applications that require yaw rate and acceleration signals simultaneously. An internal temperature sensor compensates offset and sensitivity performance, providing excellent stability over the −40°C to +105°C temperature range.A digital serial port interface (SPI) transmits the yaw rate and acceleration data to a host microcontroller. A 4-bit cyclical redundancy check (CRC) provides fault coverage for the transmitted SPI data, and internal fault detection routines ensure the integrity of all reported yaw rates and acceleration data. A fully integrated electromechanical continuous self test (CST) routine provides run-time diagnostic capability for assessing the health of each MEMS element.An advanced gyroscope sensor design rejects the linear acceleration effects of shock and vibration, enabling the ADXC1500 to operate in harsh environments. The accelerometer signal chain is designed to prevent overload conditions from occurring in these same harsh environments.The ADXC1500 is designed to operate at either 3.3 V or 5 V. At less than 16 mA current consumption, the ADXC1500 can be used in energy sensitive applications.ApplicationsElectronic stability controlChassis control

The ADXL1004 delivers ultralow noise density over an extended frequency range and is optimized for bearing fault detection and diagnostics. The ADXL1004 has typical noise density of 125 μg/√Hz across the linear frequency range. Microelectronicmechanical systems (MEMS) accelerometers have stable and repeatable sensitivity, and are immune to external shocks up to 10,000g.The integrated signal conditioning electronics enable such features as full electrostatic self test (ST) and an overrange (OR) indicator, useful for embedded applications. With low power and single-supply operation of 3.3 V to 5.25 V, the ADXL1004 also enables wireless sensing product design. The ADXL1004 is available in a 5 mm × 5 mm × 1.80 mm LFCSP package, and operates over the −40°C to +125°C temperature range.ApplicationsCondition monitoringPredictive maintenanceAsset healthTest and measurementHealth usage monitoring system (HUMSs)Acoustic emissions
