Programmable power management Embedded temperature sensor SPI-compatible serial interface Auxiliary, 12-bit ADC input and DAC output Single-supply operation: 4.75 V to 5.25 V 2000 g shock survivability Operating temperature range: 40C to +85C APPLICATIONS Medical instrumentation Robotics Platform control Navigation GENERAL DESCRIPTION The ADIS16300 iSensor is a complete inertial system that investment associated with discrete designs. All necessary includes a yaw rate gyroscope and tri-axis accelerometer. Each motion testing and calibration are part of the production sensor in the ADIS16300 combines industry-leading iMEMS process at the factory, greatly reducing system integration time. technology with signal conditioning that optimizes dynamic Tight orthogonal alignment simplifies inertial frame alignment performance. The factory calibration characterizes each sensor in navigation systems. An improved SPI interface and register for sensitivity, bias, alignment, and linear acceleration (gyro bias). structure provide faster data collection and configuration control. As a result, each sensor has its own dynamic compensation for The ADIS16300, along with a flex interface, drops into current correction formulas that provide accurate sensor measurements systems that use the ADIS1635x family, providing the opportunity over the specified power supply range of +4.75 V to +5.25 V. to scale cost for systems that only require four degrees of The ADIS16300 provides a simple, cost-effective method for freedom inertial sensing. This compact module is approximately integrating accurate, multi-axis, inertial sensing into industrial 23 mm 31 mm 7.5 mm and provides a standard connector systems, especially when compared with the complexity and interface, which enables horizontal or vertical mounting.
