FEATURES
GENERAL DESCRIPTION
Dual axis accelerometer on a single IC chip
5 mm × 5 mm × 2 mm LCC package
1 mg resolution at 60 Hz
Low power: 700 µA at VS = 5 V (typical)
High zero g bias stability
The ADXL213 is a low cost, low power, complete dual axis
accelerometer with signal conditioned, duty cycle modulated
outputs, all on a single monolithic IC. The ADXL213 measures
acceleration with a full-scale range of 1.2 g (typical). The
ADXL213 can measure both dynamic acceleration (e.g.,
vibration) and static acceleration (e.g., gravity).
High sensitivity accuracy
Pulse width modulated digital outputs
X and Y axes aligned to within 0.1° (typical)
BW adjustment with a single capacitor
Single-supply operation
The outputs are digital signals whose duty cycles (ratio of pulse
width to period) are proportional to acceleration (30%/g). The
duty cycle outputs can be directly measured by a microcontrol-
ler without an A/D converter or glue logic.
3500 g shock survival
Innovative design techniques are used to ensure high zero g bias
stability (typically better than 0.25 mg/°C), as well as tight sensi-
tivity stability (typically better than 50 ppm/°C).
APPLICATIONS
Automotive tilt alarms
Data projectors
Navigation
The typical noise floor is 160 µg/√ , allowing signals below
Hz
1 mg (0.06° of inclination) to be resolved in tilt sensing applica-
tions using narrow bandwidths (<60 Hz).
Platform stabilization/leveling
Alarms and motion detectors
High accuracy, 2-axis tilt sensing
The user selects the bandwidth of the accelerometer using
capacitors CX and CY at the XFILT and YFILT pins. Bandwidths of
0.5 Hz to 250 Hz may be selected to suit the application.
The ADXL213 is available in a 5 mm × 5 mm × 2 mm, 8-pad
hermetic LCC package.

The ADXL213 is a complete dual axis acceleration measure-
ment system on a single monolithic IC. It contains a polysilicon
surface-micromachined sensor and signal conditioning
circuitry to implement an open-loop acceleration measurement
architecture. The output signals are duty cycle modulated digital
signals proportional to acceleration. The ADXL213 is capable of
measuring both positive and negative accelerations to 1.2 g.
The accelerometer can measure static acceleration forces such
as gravity, allowing the ADXL213 to be used as a tilt sensor.
After being low-pass filtered, the duty cycle modulator converts
the analog signals to duty cycle modulated outputs that can be
read by a counter. A single resistor (RSET) sets the period for a
complete cycle. A 0 g acceleration produces a 50% nominal duty
cycle. The acceleration can be determined by measuring the
length of the positive pulse width (t1) and the period (t2). The
nominal transfer function of the ADXL213 is
Acceleration = ((t1/t2) – Zero g Bias)/Sensitivity
Where in the case of the ADXL213
Zero g Bias = 50% nominal
The sensor is a surface-micromachined polysilicon structure
built on top of the silicon wafer. Polysilicon springs suspend the
structure over the surface of the wafer and provide a resistance
against acceleration forces. Deflection of the structure is mea-
sured using a differential capacitor that consists of independent
fixed plates and plates attached to the moving mass. The fixed
plates are driven by 180° out-of-phase square waves. Accelera-
tion deflects the beam and unbalances the differential capacitor,
resulting in an output square wave whose amplitude is propor-
tional to acceleration. Phase sensitive demodulation techniques
are then used to rectify the signal and determine the direction
of the acceleration.
Sensitivity = 30%/g nominal
t2 = RSET/125 MΩ
PERFORMANCE
Rather than using additional temperature compensation
circuitry, innovative design techniques have been used to ensure
that high performance is built in. As a result, there is essentially
no quantization error or nonmonotonic behavior, and
temperature hysteresis is very low (typically less than 10 mg
over the –40°C to +85°C temperature range).
The output of the demodulator is amplified and brought off-
chip through a 32 kΩ resistor. At this point, the user can set the
signal bandwidth of the device by adding a capacitor. This
filtering improves measurement resolution and helps prevent
aliasing.
Figure 9 shows the zero g output performance of eight parts (X
and Y axis) over a –40°C to +85°C temperature range.
Figure 12 demonstrates the typical sensitivity shift over
temperature for VS = 5 V. Sensitivity stability is optimized for
VS = 5 V, but is still very good over the specified range; it is
typically better than 2% over temperature at VS = 3 V.

APPLICATIONS
POWER SUPPLY DECOUPLING
DESIGN TRADE-OFFS FOR SELECTING FILTER
CHARACTERISTICS: THE NOISE/BW TRADE-OFF
For most applications, a single 0.1 µF capacitor, CDC, adequately
decouples the accelerometer from noise on the power supply.
However, in some cases, particularly where noise is present at
the 140 kHz internal clock frequency (or any harmonic
thereof), noise on the supply may cause interference on the
ADXL213’s output. If additional decoupling is needed, a 100 Ω
(or smaller) resistor or ferrite beads may be inserted in the
supply line of the ADXL213. Additionally, a larger bulk bypass
capacitor (in the range of 1 µF to 22 µF) may be added in
The accelerometer bandwidth selected ultimately determines
the measurement resolution (smallest detectable acceleration).
Filtering can be used to lower the noise floor, which improves
the resolution of the accelerometer. Resolution is dependent on
the analog filter bandwidth at XFILT and YFILT
.
The output of the ADXL213 has a typical bandwidth of 2.5 kHz.
The user must filter the signal at this point to limit aliasing
errors. The analog bandwidth must be no more than one-fifth
the PWM frequency to minimize aliasing. The analog
bandwidth may be further decreased to reduce noise and
improve resolution.
parallel to CDC
.
SETTING THE BANDWIDTH USING CX AND CY
The ADXL213 has provisions for bandlimiting the XOUT and
YOUT pins. Capacitors must be added at these pins to implement
low-pass filtering for antialiasing and noise reduction. The
equation for the –3 dB bandwidth is
The ADXL213 noise has the characteristics of white Gaussian
noise, which contributes equally at all frequencies and is
described in terms of µg/√ (i.e., the noise is proportional to
Hz
the square root of the accelerometer’s bandwidth). The user
should limit bandwidth to the lowest frequency needed by the
application in order to maximize the resolution and dynamic
range of the accelerometer.
F
–3 dB = 1/(2π(32 kΩ) × C(X, Y))
or more simply,
F–3 dB = 5 µF/C(X, Y)
With the single pole roll-off characteristic, the typical noise of
the ADXL213 is determined by
The tolerance of the internal resistor (RFILT) can vary typically as
much as 25% of its nominal value (32 kΩ); thus, the band-
width varies accordingly. A minimum capacitance of 2000 pF
for CX and CY is required in all cases.
rmsNoise = (160µg / Hz)×( BW ×1.6)
At 100 Hz the noise is

Often, the peak value of the noise is desired. Peak-to-peak noise
can only be estimated by statistical methods. Table 5 is useful
for estimating the probabilities of exceeding various peak
values, given the rms value.

The ST pin controls the self-test feature. When this pin is set to
VS, an electrostatic force is exerted on the beam of the accelero-
meter. The resulting movement of the beam allows the user to
test if the accelerometer is functional. The typical change in
output is 750 mg (corresponding to 23%). This pin may be left
open circuit, or may be connected to common in normal use.

The ST pin should never be exposed to voltages greater than
VS + 0.3 V. If the system design is such that this condition
cannot be guaranteed (i.e., multiple supply voltages present), a
low VF clamping diode between ST and VS is recommended.

Peak-to-peak noise values give the best estimate of the
uncertainty in a single measurement. Table 6 gives the typical
noise output of the ADXL213 for various CX and CY values.
USING THE ADXL213 AS A DUAL-AXIS TILT
SENSOR
One of the most popular applications of the ADXL213 is tilt
measurement. An accelerometer uses the force of gravity as an
input vector to determine the orientation of an object in space.

An accelerometer is most sensitive to tilt when its sensitive axis
is perpendicular to the force of gravity, i.e., parallel to the earth’s
surface. At this orientation, its sensitivity to changes in tilt is
highest. When the accelerometer is oriented on axis to gravity,
i.e., near its +1 g or –1 g reading, the change in output accelera-
tion per degree of tilt is negligible. When the accelerometer is
perpendicular to gravity, its output changes nearly 17.5 mg per
degree of tilt. At 45°, its output changes at only 12.2 mg per
degree and resolution declines.

USING THE ADXL213 WITH OPERATING
VOLTAGES OTHER THAN 5 V
The ADXL213 is tested and specified at VS = 5 V; however, it can
be powered with VS as low as 3 V or as high as 6 V. Some perfor-
mance parameters will change as the supply voltage is varied.
Dual-Axis Tilt Sensor: Converting Acceleration to Tilt
When the accelerometer is oriented so both its X and Y axes are
parallel to the earth’s surface, it can be used as a 2-axis tilt
sensor with a roll axis and a pitch axis. Once the output signal
from the accelerometer has been converted to an acceleration
that varies between –1 g and +1 g, the output tilt in degrees is
calculated as follows:
The ADXL213 output varies proportionally to supply voltage. At
VS = 3 V, the output sensitivity is typically 28%/g.
The zero g bias output is ratiometric, so the zero g output is
nominally equal to 50% at all supply voltages.
The output noise also varies with supply voltage. At VS = 3 V, the
PITCH = ASIN(AX/1 g)
ROLL = ASIN(AY/1 g)
noise density is typically 200 µg/√
.
Hz
Self-test response in g is roughly proportional to the square of
the supply voltage. So at VS = 3 V, the self-test response is
equivalent to approximately 270 mg (typical), or 8%.
Be sure to account for overranges. It is possible for the
accelerometers to output a signal greater than 1 g due to
vibration, shock, or other accelerations.
The supply current decreases as the supply voltage decreases.
Typical current consumption at VDD = 3 V is 450 µA.
