Tactical Grade, Ten Degrees of Freedom Inertial Sensor Data Sheet ADIS16488A FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope, ±450°/sec dynamic range
The ADIS16488A iSensor® device is a complete inertial system
±0.05° orthogonal alignment error
that includes a triaxis gyroscope, a triaxis accelerometer, triaxis
5.1°/hr in-run bias stability
magnetometer, and pressure sensor. Each inertial sensor in the
0.26°/√hr angular random walk
ADIS16488A combines industry-leading iMEMS® technology
0.01% nonlinearity
with signal conditioning that optimizes dynamic performance.
Triaxial, digital accelerometer, ±18 g
The factory calibration characterizes each sensor for sensitivity,
Triaxial, delta angle and delta velocity outputs
bias, alignment, and linear acceleration (gyroscope bias). As a
Triaxial, digital magnetometer, ±2.5 gauss
result, each sensor has its own dynamic compensation formulas that
Digital pressure sensor, 300 mbar to 1100 mbar
provide accurate sensor measurements.
Fast start-up time, ~500 ms
The ADIS16488A provides a simple, cost-effective method for
Factory-calibrated sensitivity, bias, and axial alignment
integrating accurate, multiaxis inertial sensing into industrial
Calibration temperature range: −40°C to +85°C
systems, especially when compared with the complexity and
SPI-compatible serial interface
investment associated with discrete designs. All necessary motion
Embedded temperature sensor
testing and calibration are part of the production process at the
Programmable operation and control
factory, greatly reducing system integration time. Tight orthogonal
Automatic and manual bias correction controls
alignment simplifies inertial frame alignment in navigation systems.
4 FIR filter banks, 120 configurable taps
The SPI and register structure provide a simple interface for
Digital input/output: data-ready alarm indicator,
data collection and configuration control.
external clock Alarms for condition monitoring
The ADIS16488A uses the same footprint and connector system as
Power-down/sleep mode for power management
the ADIS16375, ADIS16480, and ADIS16485, which greatly
Optional external sample clock input: up to 2.4 kHz
simplifies the upgrade process. The ADIS16488A is packaged in
Single command self test
a module that is approximately 47 mm × 44 mm × 14 mm and
Single-supply operation: 3.0 V to 3.6 V
includes a standard connector interface.
