1000/Sec Precision Angular Rate Sensor Data Sheet ADIS16137 FEATURES GENERAL DESCRIPTION Digital gyroscope system, 1000/sec measurement range The ADIS16137 iSensor is a high performance, digital gyro- In-run bias stability, 2.8/hour scope sensing system that operates autonomously and requires Autonomous operation and data collection no user configuration to produce accurate rate sensing data. It No external configuration commands required provides performance advantages with its low noise density, Start-up time: 245 ms wide bandwidth, and excellent in-run bias stability, which enable Sleep mode recovery: 2.5 ms applications such as platform control, navigation, robotics, and Factory calibrated sensitivity and bias medical instrumentation. Calibration temperature range: 40C to +85C This sensor system combines industry leading iMEMS technology SPI-compatible serial interface with signal conditioning that optimizes dynamic performance. Wide bandwidth: 400 Hz The factory calibration characterizes the entire sensor signal chain Embedded temperature sensor for sensitivity and bias over a temperature range of 40C to +85C. Programmable operation and control As a result, each ADIS16137 has its own unique correction Automatic and manual bias correction controls formulas to produce accurate measurements upon installation. Digital filters: Bartlett FIR, average/decimation For some systems, the factory calibration eliminates the need Internal sample rate: up to 2048 SPS for system level calibration and greatly simplifies it for others. Digital I/O: data ready, alarm indicator, general-purpose The ADIS16137 provides data at rates of up to 2048 SPS and Alarms for condition monitoring offers an averaging/decimation filter structure for optimizing noise/ Sleep mode for power management bandwidth trade-offs. The serial peripheral interface (SPI) and Enable input sync operation user register structure provide easy access to configuration controls Single-supply operation: 4.75 V to 5.25 V and calibrated sensor data for embedded processor platforms. 2000 g shock survivability Operating temperature range: 40C to +105C The 36 mm 44 mm 14 mm package provides four holes for simple mechanical attachment, using M2 (or 2-56 standard size) APPLICATIONS machine screws along with a standard 24-lead, dual row, 1 mm Precision instrumentation pitch connector that supports electrical attachment to a printed Platform stabilization and controls circuit board (PCB) or cable system. It is package and pin Industrial vehicle navigation compatible with the ADIS16133, the ADIS16135, and the Downhole instrumentation ADIS16136.
