The ADIS16362 iSensor® is a complete inertial system that includes motion testing and calibration are part of the production process a triaxis gyroscope and triaxis accelerometer. Each sensor in the at the factory, greatly reducing system integration time. Tight ADIS16362 combines industry-leading iMEMS® technology orthogonal alignment simplifies inertial frame alignment in with signal conditioning that optimizes dynamic performance. navigation systems. An improved SPI interface and register The factory calibration characterizes each sensor for sensitivity, structure provide faster data collection and configuration control. bias, alignment, and linear acceleration (gyro bias). As a result, The ADIS16362 uses a compatible pinout and the same package each sensor has its own dynamic compensation formulas that as the ADIS1635x family. Therefore, systems that currently use provide accurate sensor measurements over a temperature the ADIS1635x family can upgrade their performance with range of −20°C to +70°C. minor firmware adjustments in their processor designs. The ADIS16362 provides a simple, cost-effective method for This compact module is approximately 23 mm × 23 mm × 23 mm integrating accurate, multiaxis, inertial sensing into industrial and provides a flexible connector interface that enables multiple systems, especially when compared with the complexity and mounting orientation options. investment associated with discrete designs.
