±450°/Sec Precision Angular Rate Sensor Data Sheet ADIS16136 FEATURES GENERAL DESCRIPTION Digital gyroscope system, ±450°/sec measurement range
The ADIS16136 iSensor® is a high performance, digital gyroscope
In-run bias stability, 4°/hour
sensing system that operates autonomously and requires no
Autonomous operation and data collection
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: 180 ms; sleep mode recovery: 2.5 ms
wide bandwidth, and excellent in-run bias stability, which enable
Factory calibrated sensitivity and bias
applications such as platform control, navigation, robotics, and
Calibration temperature range: −40°C to +70°C
medical instrumentation.
SPI-compatible serial interface
This sensor system combines industry leading iMEMS® technology
Wide bandwidth: 380 Hz
with signal conditioning that optimizes dynamic performance. The
Embedded temperature sensor
factory calibration characterizes the entire sensor signal chain for
Programmable operation and control
sensitivity and bias over a temperature range of −40°C to +70°C. As
Automatic and manual bias correction controls
a result, each ADIS16136 has its own unique correction formulas
Digital filters: Bartlett FIR, average/decimation
to produce accurate measurements upon instal ation. For some
Internal sample rate: up to 2048 SPS
systems, the factory calibration eliminates the need for system
Digital I/O: data ready, alarm indicator, general-purpose
level calibration and greatly simplifies it for others.
Alarms for condition monitoring Sleep mode for power management
The ADIS16136 provides data at rates of up to 2048 SPS and
Enable input sync operation
offers an averaging/decimation filter structure for optimizing
Single-supply operation: 4.75 V to 5.25 V
noise/bandwidth trade-offs. The serial peripheral interface (SPI)
2000 g shock survivability
and user register structure provide easy access to configuration
Operating temperature range: −40°C to +85°C
controls and calibrated sensor data for embedded processor
