DESCRIPTION The ADIS16251 is a complete angular rate, measurement sys-tem, 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. The device range can be digitally selected from three different settings: 20 /sec, 40 /sec, and 80 /sec. Unique charac-teristics of the end system are accommodated easily through several built-in features, including a single-command auto-zero recalibration function, as well as a configurable sample rate and FEATURES Yaw rate gyroscope with digital range scaling 20 /sec, 40 /sec, and 80 /sec settings 14-bit digital gyroscope sensor outputs 12-bit digital temperature sensor output Calibrated sensitivity and bias In-system, auto-zero for bias drift calibration Digitally controlled sample rate Digitally controlled frequency response Dual alarm settings with configurable operation Embedded integration for short-term angle estimates Digitally activated self-test Digitally activated low power mode Interrupt-driven wake-up SPI-compatible serial interface 49 Hz sensor bandwidth Auxiliary 12-bit ADC input and 12-bit DAC output Auxiliary digital input/output Single-supply operation: 4.75 V to 5.25 V 2000 gAPPLICATIONS Instrumentation control Platform control and stabilization Motion control and analysis Avionics instrumentation Navigation Image stabilization Robotics FUNCTIONAL BLOCK DIAGRAM SCLKDINDOUTDIO1DIO2SPIPORTTEMPERATURESENSORSELF-TESTPOWERMANAGEMENTAUXILIARYI/OALARMDIGITALCONTROLSIGNALCONDI Specifications subject to change without notic
