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

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.
