Single/Dual Axis Accelerometer
ADXL±03/ADXL203
GENERAL DESCRIPTION
FEATURES
High performance, single/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 ADXL103/ADXL203 are high precision, low power,
complete single and dual axis accelerometers with signal
conditioned voltage outputs, all on a single monolithic IC. The
ADXL103/ADXL203 measures acceleration with a full-scale
range of 1.ꢀ g . The ADXL103/ADXL203 can measure both
dynamic acceleration (e.g., vibration) and static acceleration
(e.g., gravity).
High sensitivity accuracy
–40°C to +125°C temperature range
X and Y axes aligned to within 0.1° (typical)
BW adjustment with a single capacitor
Single-supply operation
The typical noise floor is 110 μg/√Hz, allowing signals below
1 mg (0.06° of inclination) to be resolved in tilt sensing
applications using narrow bandwidths (<60 Hz).
3500 g shock survival
The user selects the bandwidth of the accelerometer using
capacitors CX and CY at the XOUT and YOUT pins. Bandwidths of
0.5 Hz to 2.5 kHz may be selected to suit the application.

The ADXL103/ADXL203 are complete acceleration measure-
ment systems on a single monolithic IC. The ADXL103 is a
single axis accelerometer, while the ADXL203 is a dual axis
accelerometer. Both parts contain a polysilicon surface-
micromachined sensor and signal conditioning circuitry to
implement an open-loop acceleration measurement architec-
ture. The output signals are analog voltages proportional to
acceleration. The ADXL103/ADXL203 are capable of measuring
both positive and negative accelerations to at least 1.ꢀ g. The
accelerometer can measure static acceleration forces such as
gravity, allowing it to be used as a tilt sensor.
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.
PERFORMANCE
Rather than using additional temperature compensation
circuitry, innovative design techniques have been used to ensure
high performance is built in. As a result, there is essentially no
quantization error or non-monotonic behavior, and
temperature hysteresis is very low (typically less than 10 mg
over the –40°C to +125°C temperature range).
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 will deflect the beam and unbalance the differential
capacitor, resulting in an output square wave whose amplitude
is proportional to acceleration. Phase sensitive demodulation
techniques are then used to rectify the signal and determine the
direction of the acceleration.
Figure 9 shows the zero g output performance of eight parts (X
and Y axis) over a –40°C to +125°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 1ꢁ 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, will
adequately decouple the accelerometer from noise on the power
supply. However in some cases, particularly where noise is pre-
sent at the 140 kHz internal clock frequency (or any harmonic
thereof), noise on the supply may cause interference on the
ADXL103/ADXL203 output. If additional decoupling is needed,
a 100 Ω (or smaller) resistor or ferrite beads may be inserted in
the supply line of the ADXL103/ADXL203. Additionally, a
larger bulk bypass capacitor (in the 1 µF to 22 µF range) may be
The accelerometer bandwidth selected will ultimately
determine 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 XOUT and YOUT
.
The output of the ADXL103/ADXL203 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
half the A/D sampling frequency to minimize aliasing. The
analog bandwidth may be further decreased to reduce noise and
improve resolution.
added in parallel to CDC
.
SETTING THE BANDWIDTH USING CX AND CY
The ADXL103/ADXL203 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 ADXL103/ADXL203 noise has the characteristics of white
Gaussian noise, which contributes equally at all frequencies and
is described in terms of µg/√Hz (i.e., the noise is proportional to
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 ADXL103/ADXL203 is determined by
The tolerance of the internal resistor (RFILT) can vary typically as
much as 25ꢁ of its nominal value (32 kΩ); thus, the band-
width will vary accordingly. A minimum capacitance of 2000 pF
for CX and CY is required in all cases.
rmsNoise = (110µg/ Hz )×( BW ×1.6)
At 100 Hz, the noise is

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 will be ꢀ50 mg (corresponding to ꢀ50 mV). This pin may

The ST pin should never be exposed to voltage greater than

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 ADXL103/ADXL203 for various CX and CY
values.
USING THE ADXL203 AS A DUAL-AXIS TILT
SENSOR
One of the most popular applications of the ADXL203 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
acceleration per degree of tilt is negligible. When the

accelerometer is perpendicular to gravity, its output will change
nearly 1ꢀ.5 mg per degree of tilt. At 45°, its output changes at
only 12.2 mg per degree and resolution declines.
USING THE ADXL103/ADXL203 WITH OPERATING
VOLTAGES OTHER THAN 5 V
The ADXL103/ADXL203 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 performance 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 axis and Y axis
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 ADXL103/ADXL203 output is ratiometric, so the output
sensitivity (or scale factor) will vary proportionally to supply
voltage. At VS = 3 V the output sensitivity is typically 560 mV/g.
The zero g bias output is also ratiometric, so the zero g output is
nominally equal to VS/2 at all supply voltages.
PITCH = ASIN(AX/1 g)
ROLL = ASIN(AY/1 g)
The output noise is not ratiometric but is absolute in volts;
therefore, the noise density decreases as the supply voltage
increases. This is because the scale factor (mV/g) increases
while the noise voltage remains constant. At VS = 3 V, the noise
density is typically 190 µg/√Hz.
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.
Self-test response in g is roughly proportional to the square of
the supply voltage. However, when ratiometricity of sensitivity
is factored in with supply voltage, self-test response in volts is
roughly proportional to the cube of the supply voltage. So at
VS = 3 V, the self-test response will be approximately equivalent
to 150 mV, or equivalent to 2ꢀ0 mg (typical).
The supply current decreases as the supply voltage decreases.
Typical current consumption at VDD = 3 V is 450 µA.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
