The size of the electronic control unit required for automotive safety systems can be reduced.

ADI has launched the ADXC150x family of inertial combo sensors. These products not only provide stability and accuracy in terms of footprint but also demonstrate shock and vibration resistance. System designers can reduce the size of electronic control units required for modern automotive safety systems based on the integrated performance of up to four degrees of freedom provided by a single device.



The ADXC150x combo sensor family has overcome potential problems that can arise when integrating automotive-grade gyroscopes and accelerometers into a single package. By enabling up to four degrees of freedom in a single device, it is possible to reduce the number of components and scale back existing integration processes that waste time and money, as well as improve inertial sensing accuracy and stability.

The yaw axis gyro drift with temperature is 1°/s (typ), and an internal temperature sensor corrects the results to provide stability over the temperature range (−40°C to 105°C) achievable in automobiles. Born from Analog Devices' commitment to ensuring functional safety, the ADXC150x also features comprehensive electromechanical failure safety devices to guarantee data integrity and is characterized by continuous monitoring.

Based on ADI's patented differential quad sensor design, the ADXC150x gyroscope effectively eliminates linear acceleration, such as external G-forces and vibrations. ADI's latest accelerometers provide noise cancellation, performance, and a wide dynamic range with a sensor beam design featuring a low Q value, enabling the output of stable overload signals.

Internally, two configurations are available. One is the ADXC1500, a 2-axis accelerometer equipped with a yaw gyroscope, and the other is the ADXC1501, a 3-axis accelerometer equipped with a yaw gyroscope. Both configurations provide digital outputs for serial peripheral interfaces and are provided in a 16-lead inverted cavity SOIC package for stable electromagnetic interference noise management performance.
