GENERAL DESCRIPTION

The ADIS16501 is a precision, miniature microelectromechanical

system (MEMS) inertial measurement unit (IMU) that includes

a triaxial gyroscope and a triaxial accelerometer. Each inertial

sensor in the ADIS16501 combines with signal conditioning that

optimizes dynamic performance. The factory calibration characterizes

each sensor for sensitivity, bias, alignment, linear acceleration

(gyroscope bias), and point of percussion (accelerometer location).

The ADIS16501 provides a simplified, cost-effective method for integrating

accurate, multiaxis 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 serial

peripheral interface (SPI) and register structure provide a simple

interface for data collection and configuration control.
