The ADXC1501 is a yaw rate gyroscope and three-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 ADXC1501 to operate in harsh environments. The accelerometer signal chain is designed to prevent overload conditions from occurring in these same harsh environments.
The ADXC1501 is designed to operate at either 3.3 V or 5 V. At less than 16 mA current consumption, the ADXC1501 can be used in energy sensitive applications.

Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
