FEATURES
GENERAL DESCRIPTION
Dual axis accelerometer on a single IC chip
5 mm × 5 mm × 2 mm LCC package
5 mg resolution at 60 Hz
Low power: 700 μA at VS = 5 V (typical)
High zero g bias stability
The ADXL212 is a high precision, low power, complete dual
axis accelerometer with signal conditioned, duty cycle modulated
outputs, all on a single monolithic IC. The ADXL212 measures
acceleration with a full-scale range of 2 g (typical). The ADXL212
measures both dynamic acceleration (such as vibration) and
static acceleration (such as gravity).
High sensitivity accuracy
Pulse width modulated digital outputs
X- and Y-axis aligned to within 0.1° (typical)
Bandwidth 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 (12.5%/g) in
each of the two sensitive axes. The duty cycle outputs can be
directly measured by a microcontroller without an analog-to-
digital converter (ADC) or glue logic. The output period is
adjustable from 0.5 ms to 10 ms via a single resistor (RSET).
3500 g shock survival
APPLICATIONS
Automotive tilt alarms
Vehicle dynamic control (VDC)/electronic stability program
(ESP) systems
The typical noise floor is 500 μg/√Hz, allowing signals below
5 mg (0.3° of inclination) to be resolved in tilt sensing applica-
tions using narrow bandwidths (<60 Hz).
Electronic chassis control
Electronic braking
Data projectors
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 500 Hz can be selected to suit the application.
Navigation
The ADXL212 is available in a 5 mm × 5 mm × 2 mm, 8-lead
hermetic LCC package.

The ADXL212 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 archi-
tecture. The output signals are duty cycle modulated digital
signals proportional to the acceleration. The ADXL212 is capable
of measuring both positive and negative accelerations to 2 g.
The accelerometer can measure static acceleration forces such
as gravity, allowing the ADXL212 to be used as a tilt sensor.
A single resistor (RSET) sets the period for a complete cycle (t2)
according to the following equation:
t2 (nominal) = RSET/125 Mꢁ
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 ADXL212 is
Acceleration = ((t1/t2) − Zero g Bias)/Sensitivity
The sensor is a surface-micromachined polysilicon structure
built on top of a 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 measured
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. Acceleration
deflects the beam and unbalances the differential capacitor,
resulting in an output square wave with an amplitude that is
proportional to acceleration. Phase sensitive demodulation tech-
niques are used to rectify the signal and determine the direction
of the acceleration.
where:
Zero g Bias = 50% nominal.
Sensitivity = 12.5%/g nominal.
PERFORMANCE
High performance is built into the device through innovative
design techniques rather than by using additional temperature
compensation circuitry. As a result, there is essentially no quantiza-
tion error or nonmonotonic behavior, and temperature hysteresis
is very low (typically less than 10 mg over the −40°C to +85°C
temperature range).
Figure 10 shows the zero g output performance of eight parts
(x-axis and y-axis) over a –40°C to +85°C temperature range.
The output of the demodulator is amplified and brought off
chip through a 32 kΩ resistor, at which 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 13 demonstrates the typical sensitivity shift over temper-
ature for VS = 5 V. Sensitivity stability is optimized for VS = 5 V
but remains very good over the specified range; it is typically
better than 2% over temperature at VS = 3 V.
After being low-pass filtered, the analog signals are converted to
duty cycle modulated outputs that can be read by a counter.

APPLICATIONS INFORMATION
DESIGN TRADE-OFFS FOR SELECTING FILTER
CHARACTERISTICS: NOISE vs. BANDWIDTH
POWER SUPPLY DECOUPLING
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 output of the
ADXL212. If additional decoupling is needed, insert a 100 Ω (or
smaller) resistor or ferrite beads in the supply line of the ADXL212.
In addition or as an alternative to adding the resistor or ferrite
beads, a larger bulk bypass capacitor (in the range of 1 μF to
The chosen accelerometer bandwidth ultimately determines the
measurement resolution (smallest detectable acceleration). Filtering
can be used to lower the noise floor, which improves the resolu-
tion of the accelerometer. Resolution is dependent on the analog
filter capacitors at XFILT and YFILT
.
The ADXL212 has a typical PWM bandwidth of 500 Hz. The
user must filter the signal to a bandwidth lower than 500 Hz to
limit aliasing errors.
22 μF) can be added in parallel to CDC
.
The ADXL212 noise has the characteristics of white Gaussian
noise, which contributes equally at all frequencies and is described
in terms of μg/√Hz (that is, the noise is proportional to the square
root of the accelerometer bandwidth). To maximize the resolu-
tion and dynamic range of the accelerometer, limit bandwidth
to the lowest frequency needed by the application.
SETTING THE BANDWIDTH USING CX AND CY
The ADXL212 has provisions for band limiting 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
With the single pole roll-off characteristic, the typical noise of
the ADXL212 is determined by
f
3 dB = 1/(2π(32 kΩ) × C(X, Y)
or more simply,
3 dB = 5 μF/C(X, Y)
)
rms Noise = (500 μg/ Hz )×( BW ×1.6)
At 100 Hz, the noise is
f
The tolerance of the internal resistor (RFILT) can vary typically as
much as 25% of its nominal value (32 kΩ); the bandwidth varies
accordingly. A minimum capacitance of 2000 pF for CX and CY
is required in all cases.
rms Noise = (500 μg/ Hz)×( 100×1.6) = 6.3mg
Often, the peak value of the noise is desired. Peak-to-peak noise
can only be estimated by statistical methods. Table 7 is useful
for estimating the probabilities of exceeding various peak values,
given the rms value.

SELF TEST
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 a duty cycle of 10%) and is
additive to the accelerometer outputs. The ST pin can remain
open circuit, or it can be connected to ground in normal use.
For example, at 100 Hz bandwidth, peak noise exceeds 25.2 mg
4.6% of the time.
Peak-to-peak noise values provide the best estimate of the
uncertainty in a single measurement. Table 8 lists the typical
noise output of the ADXL212 for various CX and CY values.

Estimate (mg)
Never expose the ST pin to voltages greater than VS + 0.3 V. If
the system design is such that this condition cannot be guaranteed
(that is, multiple supply voltages are present), a low VF clamping
diode between ST and VS is recommended.

ADXL±1±
An accelerometer is most sensitive to tilt when its sensitive axis
is perpendicular to the force of gravity, that is, parallel to the
surface of the earth. At this orientation, its response to changes
in tilt is highest: its output changes nearly 17.5 mg per degree of
tilt. When the accelerometer is oriented on axis to gravity, that
is, near its +1 g or –1 g reading, the change in output acceleration
per degree of tilt is negligible. At 45°, its output changes by
12.2 mg per degree.
USING THE ADXL212 WITH OPERATING
VOLTAGES OTHER THAN 5 V
The ADXL212 is tested and specified at VS = 5 V; however, it
can be powered with VS as low as 3 V or as high as 5.25 V. Some
performance parameters change as the supply voltage varies.
The ADXL212 sensitivity varies proportionally to supply
voltage. At VS = 3 V, the sensitivity is typically 7.5%/g.
The zero g bias output is ratiometric to supply voltage;
therefore, the zero g output is nominally equal to 50% at all
supply voltages.
Dual Axis Tilt Sensor: Converting Acceleration to Tilt
When the accelerometer is oriented with both its x-axis and
y-axis parallel to the surface of the earth (reading approximately
0 g), it can be used as a dual axis tilt sensor with a roll axis and a
pitch axis. The output tilt in degrees is calculated as follows:
Self test response in g is roughly proportional to the square of
the supply voltage. Therefore, at VS = 3 V, the self test response
is equivalent to approximately 270 mg (typical), or 6%.
Pitch = ASIN(AX/1 g)
The supply current decreases as the supply voltage decreases.
Typical current consumption at VDD = 3 V is 450 μA.
Roll = ASIN(AY/1 g)
where AX and AY are accelerations in g, ranging from −1 g to +1 g.
USING THE ADXL212 AS A DUAL AXIS TILT
SENSOR
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.
A common application of the ADXL212 is tilt measurement. An
accelerometer uses the force of gravity as an input vector to deter-
mine its orientation in space.
