GENERAL DESCRIPTION The ADIS16250/ADIS16255 are complete angular rate meas- The device range can be digitally selected from three different urement systems available in a single compact package enabled settings: 80/sec, 160/sec, and 320/sec. Unique charac- by Analog Devices, Inc. iSensor integration. By enhancing teristics of the end system are accommodated easily through Analog Devices iMEMS sensor technology with an embedded several built-in features, including a single-command auto-zero signal processing solution, the ADIS16250/ADIS16255 provide recalibration function, as well as configurable sample rate and factory-calibrated and tunable digital sensor data in a convenient frequency response. Additional features can be used to further format that can be accessed using a simple SPI serial interface. reduce system complexity, including: The ADIS16255 additionally provides an extended temperature Configurable alarm function calibration. The SPI interface provides access to measurements Auxiliary 12-bit ADC and DAC for the gyroscope, temperature, power supply, and one auxiliary analog input. Easy access to calibrated digital sensor data Two configurable digital I/O ports provides developers with a system-ready device, reducing Digital self-test function development time, cost, and program risk. System power dissipation can be optimized via the ADIS16250/ ADIS16255 power management features, including an interrupt- driven wake-up. The ADIS16250/ADIS16255 are available in an 11 mm 11 mm 5.5 mm, laminate-based land grid array (LGA) package with a temperature range of 40C to +85C. Rev.
