ADXC1500AWBRGZ-RL GENERAL DESCRIPTION

The ADXC1500 is a yaw rate gyroscope and dual-axisaccelerometer combined in a single package. It is designed forelectronic stability control (ESC) and other high performanceapplications that require yaw rate and acceleration signals simultan-eously. An internal temperature sensor compensates offset andsensitivity performance, providing excellent stability over the−40°C to +105°C temperature range.A digital serial port interface (SPI) transmits the yaw rate andacceleration data to a host microcontroller. A 4-bit cyclicalredundancy check (CRC) provides fault coverage for thetransmitted SPI data, and internal fault detection routinesensure the integrity of all reported yaw rates and accelerationdata. A fully integrated electromechanical continuous self test(CST) routine provides run-time diagnostic capability forassessing the health of each MEMS element.An advanced gyroscope sensor design rejects the linear accel-eration effects of shock and vibration, enabling the ADXC1500to operate in harsh environments. The accelerometer signalchain is designed to prevent overload conditions fromoccurring in these same harsh environments.The ADXC1500 is designed to operate at either 3.3 V or 5 V. Atless than 16 mA current consumption, the ADXC1500 can beused in energy sensitive applications.
