±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 excel ent 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: −40°C to +85°C
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 −40°C to +85°C.
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 instal ation.
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 Alarms for condition monitoring
The ADIS16137 provides data at rates of up to 2048 SPS and
Sleep mode for power management
offers an averaging/decimation filter structure for optimizing noise/
Enable input sync operation
bandwidth trade-offs. The serial peripheral interface (SPI) and
Single-supply operation: 4.75 V to 5.25 V
user register structure provide easy access to configuration controls
2000 g shock survivability
and calibrated sensor data for embedded processor platforms.
Operating temperature range: −40°C to +105°C
The 36 mm × 44 mm × 14 mm package provides four holes for
