ADIS16120
GENERAL DESCRIPTION
The ADIS16120 is a low noise, angular rate sensor (gyroscope)
that includes all of the necessary embedded signal conditioning
to provide a low noise, analog output over the complete dynamic
range of ±300^o/sec. Factory calibration provides excellent offset
and gain accuracy. The unique design implementation provides
superior stability over variations in temperature, voltage, linear
acceleration, vibration, and next level assembly. The surface-
micromachining manufacturing technology is the same high
volume BiMOS process used by Analog Devices, Inc. for its high
reliability automotive sensor products.
The output signal, RATEOUT, is a voltage proportional to the
angular rate about the axis normal to the top surface of the
package. A precision reference and a temperature output are
provided for system level calibrations and a digital self-test
feature is provided to enable system-level diagnostics. The self-
test function electromechanically excites the sensor to verify
proper operation.
The 35.6 mm × 42.4 mm (plus mounting extensions) package
provides the convenience of a standard geometry 24-pin interface
and four mounting holes for simple installation. Consult the
factory for additional dynamic range and sensitivity options.
