The ADIS16488A iSensor device is a complete inertial system that includes a triaxis gyroscope, a triaxis accelerometer, triaxis magnetometer, and pressure sensor. Each inertial sensor in the ADIS16488A combines Analog’s iMEMS technology with signal conditioning that optimises dynamic performance. The factory calibration characterises each sensor for sensitivity, bias, alignment, and linear acceleration (gyroscope bias). As a result, each sensor has its own dynamic compensation formulae that provide accurate sensor measurements.
The ADIS16488A, ADI says, provides a simple, cost-effective method for integrating accurate, multi-axis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The SPI and register structure provide a simple interface for data collection and configuration control.
The ADIS16488A uses the same footprint and connector system as the ADIS16375, ADIS16480, ADIS16485, and ADIS16488, which simplifies the upgrade process. The ADIS16488A is packaged in a module that is approximately 47 × 44 × 14 mm and includes a standard connector interface.
