FEATURES
GENERAL DESCRIPTION
Triaxial digital gyroscope, 450°/sec dynamic range
(minimum)
The ADIS16486 is a complete inertial system that includes a triaxis
gyroscope and a triaxis accelerometer. Each inertial sensor in the
ADIS16486 combines industry leading iMEMS® technology with
signal conditioning that optimizes dynamic performance. The
factory calibration characterizes each sensor for sensitivity, bias,
alignment, and linear acceleration (gyroscope bias). Therefore,
each sensor has dynamic compensation formulas that provide
accurate sensor measurements.
0.018° axis to axis misalignment error (typical)
5.3°/hr in-run bias stability (typical)
0.25°/√hr angular random walk (typical)
0.01% FS nonlinearity
Triaxial digital accelerometer, 18 g dynamic range
(minimum)
Triaxial, delta angle, and delta velocity outputs
The ADIS16486 provides a simple, cost effective method for
Factory calibrated sensitivity, bias, and axial alignment
Calibration temperature range: −40°C to +85°C
SPI compatible
Programmable operation and control
Automatic and manual bias correction controls
4 FIR filter banks, 120 configurable taps
Digital input and output: data ready alarm indicator,
external clock
integrating accurate, multiaxis inertial sensing into industrial
systems, especially when compared with the complexity and
investment associated with discrete designs. All necessary motion
testing and calibration are part of the production process at the
factory, which reduces system integration time. Tight orthogonal
alignment simplifies inertial frame alignment in navigation
systems. The serial peripheral interface (SPI) and register structure
provide a simple interface for data collection and configuration
control. Parylene coating of all internal circuitry provides a
protective barrier against moisture exposure.
Alarms for condition monitoring
Power-down and sleep mode for power management
Optional external sync input clock: 2.4 kHz (maximum)
Continuous self test of inertial sensors
On demand self test of inertial sensors
Continuous CRC-based memory testing
Single VDD power supply operation: 3.0 V to 3.6 V
2000 g mechanical shock survivability
Operating temperature range: −40°C to +105°C
The ADIS16486 uses the same footprint and connector system as
the ADIS16480, ADIS16485, ADIS16487, and ADIS16488A, which
greatly simplifies the upgrade process. The ADIS16486 is packaged
in a module that is approximately 47 mm × 44 mm × 14 mm with
a 24-lead standard connector interface.
