The ADXRS646 is a high performance angular rate sensor
(gyroscope) that offers excellent vibration immunity. Bias
stability is a widely-recognized figure of merit for high
performance gyroscopes, but in real-world applications,
vibration sensitivity is often a more significant performance
limitation and should be considered in gyroscope selection. The
ADXRS646 offers superior vibration immunity and acceleration
rejection as well as a low bias drift of 12°/hr (typical), enabling it
to offer rate sensing in harsh environments where shock and
vibration are present.
The ADXRS646 is manufactured using the Analog Devices,
Inc., patented high volume BiMOS surface-micromachining
process. An advanced, differential, quad sensor design provides
the improved acceleration and vibration rejection. The output
signal, RATEOUT, is a voltage proportional to angular rate
about the axis normal to the top surface of the package. The
measurement range is a minimum of ±250°/sec. The output is
ratiometric with respect to a provided reference supply. Other
external capacitors are required for operation.
APPLICATIONS
Industrial applications
Severe mechanical environments
Platform stabilization
A temperature output is provided for compensation techniques.
Two digital self-test inputs electromechanically excite the sensor
to test proper operation of both the sensor and the signal conditioning circuits.
The ADXRS646 is available in a 7 mm × 7 mm × 3 mm CBGA
chip-scale package.

ADXRS646
THEORY OF OPERATION
The ADXRS646 operates on the principle of a resonator
gyroscope. Figure 19 shows a simplified version of one of
four polysilicon sensing structures. Each sensing structure
contains a dither frame that is electrostatically driven to
resonance. This produces the necessary velocity element to
produce a Coriolis force when experiencing angular rate. The
ADXRS646 is designed to sense a Z-axis (yaw) angular rate.
SETTING BANDWIDTH
When the sensing structure is exposed to angular rate, the
resulting Coriolis force couples into an outer sense frame,
which contains movable fingers that are placed between fixed
pickoff fingers. This forms a capacitive pickoff structure that
senses Coriolis motion. The resulting signal is fed to a series of
gain and demodulation stages that produce the electrical rate
signal output. The quad sensor design rejects linear and angular
acceleration, including external g-forces, shock, and vibration.
The rejection is achieved by mechanically coupling the four
sensing structures such that external g-forces appear as
common-mode signals that can be removed by the fully
differential architecture implemented in the ADXRS646.
and can be well controlled because ROUT is trimmed during
manufacturing to 180 kΩ ± 1%. Any external resistor applied
between the RATEOUT pin (1B, 2A) and SUMJ pin (1C, 2C)
results in
The combination of an external capacitor (COUT) and the
on-chip resistor (ROUT) creates a low-pass filter that limits the
bandwidth of the ADXRS646 rate response. The −3 dB
frequency set by ROUT and COUT is
fOUT = 1/(2 × π × ROUT × COUT)
ROUT = (180 kΩ × REXT)/(180 kΩ + REXT)
An additional external filter is often added (in either hardware
or software) to attenuate high frequency noise arising from
demodulation spikes at the 18 kHz resonant frequency of the
gyroscope. An RC output filter consisting of a 3.3 kΩ series
resistor and 22 nF shunt capacitor (2.2 kHz pole) is
recommended.
TEMPERATURE OUTPUT AND CALIBRATION
It is common practice to temperature-calibrate gyroscopes
to improve their overall accuracy. The ADXRS646 has a
temperature-dependent voltage output that provides input
to such a calibration method. The temperature sensor structure
is shown in Figure 20. The temperature output is characteristically nonlinear, and any load resistance connected to the
TEMP output results in decreasing the TEMP output and its
temperature coefficient. Therefore, buffering the output is
recommended.

Figure 19. Simplified Gyroscope Sensing Structure—One Corner
The electrostatic resonator requires 21 V for operation. Because
only 6 V are typically available in most applications, a charge
pump is included on chip. If an external 21 V supply is
available, the two capacitors on CP1 to CP4 can be omitted,
and this supply can be connected to CP5 (Pin 6D, Pin 7D).
CP5 should not be grounded when power is applied to the
ADXRS646. No damage occurs, but under certain conditions,
the charge pump may fail to start up after the ground is removed
without first removing power from the ADXRS646.

The voltage at TEMP (3F, 3G) is nominally 2.9 V at 25°C, and
VRATIO = 6 V. The temperature coefficient is 10 mV/°C (typical)
at 25°C; the output response over the full temperature range is
shown in Figure 17. Although the TEMP output is highly
repeatable, it has only modest absolute accuracy.

SUPPLY RATIOMETRICITY
CONTINUOUS SELF-TEST
The null output voltage (RATEOUT), sensitivity, self-test
responses (ST1 and ST2), and temperature output (TEMP)
of the ADXRS646 are ratiometric to VRATIO. Therefore, using
the ADXRS646 with a supply-ratiometric ADC results in selfcancellation of errors resulting from minor supply variations.
There remains a small, usually negligible, error due to nonratiometric behavior. Note that, to guarantee full measurement
range, VRATIO should not be greater than AVCC.
The on-chip integration of the ADXRS646, as well as the
mature process with which it is manufactured, have provided
the gyroscope with field-proven reliability.
NULL ADJUSTMENT
The nominal 3.0 V null output voltage is true for a symmetrical
swing range at RATEOUT (1B, 2A). However, an asymmetric
output swing may be suitable in some applications. Null adjustment is possible by injecting a suitable current to SUMJ (1C, 2C).
Note that supply disturbances may cause some null instability.
Digital supply noise should be avoided, particularly in this case.
SELF-TEST FUNCTION
The ADXRS646 includes a self-test feature that actuates each
of the sensing structures and associated electronics in the same
manner as if the gyroscope were subjected to angular rate.
As an additional failure detection measure, self-test can be
performed at power-up or occasionally during operation. However,
some applications may require continuous self-test while sensing
rotation rate. Details outlining continuous self-test techniques
are available in the AN-768 Application Note, Using the
ADXRS150/ADXRS300 in Continuous Self-Test Mode. Although
the title of this application note refers to other Analog Devices
gyroscopes, the techniques apply equally to the ADXRS646.
MODIFYING THE MEASUREMENT RANGE
The ADXRS646 scale factor can be reduced to extend the
measurement range to as much as ±450°/sec by adding a
single 225 kΩ resistor between RATEOUT and SUMJ. If
an external resistor is added between RATEOUT and SUMJ,
COUT must be proportionally increased to maintain correct
bandwidth.
Self-test is activated by applying the standard logic high level ST1
pin (5F, 5G), the ST2 pin (4F, 4G), or both. Applying a logic high
to Pin ST1 causes the voltage at RATEOUT to change by −450 mV
(typical), and applying a logic high to Pin ST2 causes an opposite
change of +450 mV (typical). The voltage applied to the ST1 and
ST2 pins must never be greater than AVCC. The self-test response
follows the temperature dependence of the viscosity of the
package atmosphere, approximately 0.25%/°C.
Activating both ST1 and ST2 simultaneously is not damaging.
The output responses generated by ST1 and ST2 are closely
matched (±2%), but actuating both simultaneously may result
in a small apparent null bias shift proportional to the degree of
self-test mismatch.

ADXRS646
Gyroscopes are designed to respond only to rotation. However,
all gyroscopes respond to linear motion as well, to varying
degrees. While bias stability is often used as the primary figure
of merit for evaluating high performance gyroscopes, many
additional error sources are present in real-world applications.
Especially in applications that require motion sensors, vibration
and acceleration are present, and the resulting errors often
overwhelm bias drift.
Its differential, quad-sensor design makes the ADXRS646
inherently resistant to vibration, without the need for
compensation. The excellent vibration immunity of the
ADXRS646 is demonstrated in Figure 21 and Figure 22.
Figure 21 shows the ADXRS646 output response with and
without random 15 g rms vibration applied at 20 Hz to 2 kHz.
Performance is similar regardless of the direction of input
vibration.
1
To further improve immunity to vibration and acceleration,
some g-sensitivity compensation can be performed using an
accelerometer. This technique is most successful when the
response to vibration is constant regardless of vibration
frequency. Figure 22 demonstrates the ADXRS646 dc bias
response to a 5 g sinusoidal vibration over the 20 Hz to 5 kHz
range. This figure shows that there are no sensitive frequencies
present and that vibration rectification is vanishingly small.
Accordingly, g-sensitivity compensation using an accelerometer
is possible where needed, but the inherent device performance
is sufficient for many applications.
