FEATURES
GENERAL DESCRIPTION
High performance, dual-axis accelerometer on a
single IC chip
Specified at VS = 3.3 V
5 mm × 5 mm × 2 mm LCC package
Better than 2 mg resolution at 60 Hz
Low power: 500 μA at VS = 3.3 V (typical)
High zero g bias stability
The ADXL204 is a high precision, low power, complete dual-
axis accelerometer with signal-conditioned voltage outputs, all
on a single monolithic IC. Like the ADXL203, it measures
acceleration with a full-scale range of 1.7 g; however, the
ADXL204 is tested and specified for 3.3 V supply voltage,
whereas the ADXL203 is tested and specified at 5 V. Both parts
function well over a wide 3 V to 6 V operating voltage range.
The ADXL204 can measure both dynamic acceleration (for
example, vibration) and static acceleration (for example, gravity).
High sensitivity accuracy
–40°C to +125°C temperature range
X-axis and Y-axis aligned to within 0.1° (typical)
BW adjustment with a single capacitor
Single-supply operation
The typical noise floor is 170 μg/√Hz, allowing signals below
2 mg (0.1° of inclination) to be resolved in tilt sensing
applications using narrow bandwidths (<60 Hz).
3500 g shock survival
RoHS compliant
Compatible with Sn/Pb- and Pb-free solder processes
The user selects the bandwidth of the accelerometer using
Capacitor CX and Capacitor CY at the XOUT and YOUT pins.
Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the
application.
APPLICATIONS
Vehicle dynamic control (VDC)/electronic stability program
(ESP) systems
Electronic chassis controls

Figure 22. Output Response vs. Orientation
The ADXL204 is a complete acceleration measurement system on
a single monolithic IC. The ADXL204 is a dual-axis accelerometer.
It contains a polysilicon surface-micromachined sensor and
signal conditioning circuitry to implement an open-loop
acceleration measurement architecture. The output signals are
analog voltages proportional to acceleration. The ADXL204 is
capable of measuring both positive and negative accelerations to
at least 1.7 g. The accelerometer can measure static acceleration
forces, such as gravity, allowing it to be used as a tilt sensor.
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 nonmonotonic behavior, and temperature
hysteresis is very low, typically less than 10 mg over the –40°C
to +125°C temperature range.
Figure 10 shows the zero g output performance of eight parts
(X-axis and Y-axis) over a –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 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 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 13 demonstrates the typical sensitivity shift over tem-
perature for VS = 3.3 V. Sensitivity stability is typically better
than 1ꢀ over temperature.
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.

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 can cause interference on the ADXL204
output. If additional decoupling is needed, a 100 Ω, or smaller,
resistor or ferrite bead can be inserted in the supply line of the
ADXL204. Additionally, a larger bulk bypass capacitor, in the
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 XOUT and YOUT
.
The output of the ADXL204 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 can be further decreased to reduce noise and
improve resolution.
1 μF to 22 μF range, can be added in parallel to CDC
.
SETTING THE BANDWIDTH USING CX AND CY
The ADXL204 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 ADXL204 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’s bandwidth). The user
should limit bandwidth to the lowest frequency needed by the
application to maximize the resolution and dynamic range of
the accelerometer.
F
–3 dB = 1/(2π(32 kΩ) × C(X, Y)
or more simply,
–3 dB = 5 μF/C(X, Y)
)
F
The tolerance of the internal resistor (RFILT) can vary typically as
much as 25ꢀ 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.
With the single-pole, roll-off characteristic, the typical noise of
the ADXL204 is determined by
rmsNoise = (170 μg/√Hz) × (√BW×1.6)

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.

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 325 mg (corresponding to 200 mV). This pin can be
left open-circuit or connected to common in normal use.

The ST pin should never be exposed to voltage greater than

cannot be guaranteed (that is, 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 and is estimated by 6 × rms. Table 8
gives the typical noise output of the ADXL204 for various CX
and CY values.
USING THE ADXL204 AS A DUAL-AXIS TILT SENSOR
One of the most popular applications of the ADXL204 is tilt
measurement. An accelerometer uses the force of gravity as an
input vector to determine the orientation of an object in space.
Table 8. Filter Capacitor Selection (CX, CY)
An accelerometer is most sensitive to tilt when its sensitive
axis is perpendicular to the force of gravity, that is, 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, that is, 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 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 ADXL204 WITH OPERATING VOLTAGES
OTHER THAN 3.3 V
Dual-Axis Tilt Sensor: Converting Acceleration to Tilt
The ADXL204 is tested and specified at VS = 3.3 V; however, it
can be powered with VS as low as 3 V or as high as 6 V. Some
performance parameters change as the supply voltage is varied.
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 is converted to an acceleration
that varies between –1 g and +1 g, the output
The ADXL204 output is ratiometric, so the output sensitivity, or
scale factor, varies proportionally to supply voltage. At VS = 3 V,
the output sensitivity is typically 560 mV/g. At VS = 5 V, the
output sensitivity is typically 1000 mV/g.
tilt in degrees is calculated as:
PITCH = ASIN(AX/1 g)
ROLL = ASIN(AY/1 g)
The zero g bias output is also ratiometric, so the zero g output is
nominally equal to VS/2 at all supply voltages.
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 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. At VS = 5 V, the noise density is
typically 110 μg/√Hz.
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. This
means at VS = 3 V, the self-test response is approximately
equivalent to 150 mV, or equivalent to 270 mg (typical). At
VS = 5 V, the self-test response is approximately equivalent to
750 mV, or equivalent to 750 mg (typical).
The supply current decreases as the supply voltage decreases.
Typical current consumption at VDD = 5 V is 750 μA.
