The ADIS16251 is a complete angular rate, measurement system, available in a single compact package enabled by Analog Devices, Inc. iSensor integration. By enhancing Analog Devices iMEMS® sensor technology with an embedded signal processing solution, the ADIS16251 provides factory-calibrated and tunable digital sensor data in a convenient format that can be accessed using a simple SPI serial interface. The SPI interface provides access to measurements for the gyroscope, temperature, power supply, and one auxiliary analog input. Easy access to calibrated digital sensor data provides developers with a system-ready device, reducing development time, cost, and program risk.
