ADIS16130

Digital Output, High-Precision Angular Rate Sensor ADIS16130 FEATURES Low noise density, 0.0125o/sec/√Hz Industry-standard serial peripheral interface (SPI) 24-bit digital resolution ±250o/sec dynamic range Z-axis, yaw rate response 300 Hz bandwidth, adjustable 35 ms turn-on time Digital self-test High vibration rejection High shock survivability Embedded temperature sensor output Precision voltage reference output 5 V single-supply operation −40°C to +85°C GENERAL DESCRIPTION The ADIS16130 is a low noise, digital output angular rate sensor (gyroscope) that provides an output response over the complete dynamic range of ±250o/sec. Its industry-standard serial interface and register structure provide a simple interface that is supported by most MCU, DSP, and FPGA platforms. By implementing a unique design, the device provides superior stability over variations in temperature, voltage, linear acceleration, vibration, and next-level assembly. In addition, the surface-micromachining technology used to manufacture the device is the same high volume BiMOS process used by Analog Devices, Inc., for its high reliability automotive sensor products. Features include a temperature output that provides critical information for system-level calibrations, and a digital self-test feature, which exercises the mechanical structure of the sensor and enables system-level diagnostics. The package configuration is a 36 mm × 44 mm × 16 mm module with a standard 24-lead connector interface.
