GENERAL DESCRIPTION
The ADXL335 is a small, thin, low power, complete 3-axis accel-
erometer with signal conditioned voltage outputs. The product
measures acceleration with a minimum full-scale range of ±3 g.
It can measure the static acceleration of gravity in tilt-sensing
applications, as well as dynamic acceleration resulting from
motion, shock, or vibration.
The user selects the bandwidth of the accelerometer using the
CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
Bandwidths can be selected to suit the application, with a
range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range
of 0.5 Hz to 550 Hz for the Z axis.
The ADXL335 is available in a small, low profile, 4 mm ×
4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package
(LFCSP_LQ).

THEORY OF OPERATION
The ADXL335 is a complete 3-axis acceleration measurement
system. The ADXL335 has a measurement range of ±3 g mini-
mum. 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 that are proportional to acceleration. The
accelerometer can measure the static acceleration of gravity
in tilt-sensing applications as well as dynamic acceleration
resulting from motion, shock, or vibration.
The sensor is a polysilicon surface-micromachined 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 meas-
ured 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 moving mass and unbalances the differential capacitor
resulting in a sensor output whose amplitude is proportional to
acceleration. Phase-sensitive demodulation techniques are then
used to determine the magnitude and direction of the
acceleration.
The demodulator output is amplified and brought off-chip
through a 32 kΩ resistor. The user then sets the signal
bandwidth of the device by adding a capacitor. This filtering
improves measurement resolution and helps prevent aliasing.
MECHANICAL SENSOR
The ADXL335 uses a single structure for sensing the X, Y, and
Z axes. As a result, the three axes’ sense directions are highly
orthogonal and have little cross-axis sensitivity. Mechanical
misalignment of the sensor die to the package is the chief
source of cross-axis sensitivity. Mechanical misalignment
can, of course, be calibrated out at the system level.
PERFORMANCE
Rather than using additional temperature compensation circui-
try, innovative design techniques ensure that high performance
is built in to the ADXL335. As a result, there is no quantization
error or nonmonotonic behavior, and temperature hysteresis
is very low (typically less than 3 mg over the −25°C to +70°C
temperature range).

APPLICATIONS INFORMATION
POWER SUPPLY DECOUPLING
For most applications, a single 0.1 µF capacitor, CDC, placed
close to the ADXL335 supply pins adequately decouples the
accelerometer from noise on the power supply. However, in
applications where noise is present at the 50 kHz internal clock
frequency (or any harmonic thereof), additional care in power
supply bypassing is required because this noise can cause errors
in acceleration measurement.
If additional decoupling is needed, a 100 Ω (or smaller) resistor
or ferrite bead can be inserted in the supply line. Additionally, a
larger bulk bypass capacitor (1 µF or greater) can be added in
parallel to CDC. Ensure that the connection from the ADXL335
ground to the power supply ground is low impedance because
noise transmitted through ground has a similar effect to noise
transmitted through VS.
SETTING THE BANDWIDTH USING CX, CY, AND CZ
The ADXL335 has provisions for band limiting the XOUT, YOUT,
and ZOUT pins. Capacitors must be added at these pins to imple-
ment low-pass filtering for antialiasing and noise reduction. The
equation for the 3 dB bandwidth is
F−3 dB = 1/(2π(32 kΩ) × C(X, Y, Z ))
or more simply
F–3 dB = 5 F/C(X, Y, Z)
The tolerance of the internal resistor (RFILT) typically varies as
much as ±15% of its nominal value (32 kΩ), and the bandwidth
varies accordingly. A minimum capacitance of 0.0047 F for CX,
CY, and CZ is recommended in all cases.

SELF-TEST
The ST pin controls the self-test feature. When this pin is set to
VS, an electrostatic force is exerted on the accelerometer beam.
The resulting movement of the beam allows the user to test if
the accelerometer is functional. The typical change in output
is −1.08 g (corresponding to −325 mV) in the X-axis, +1.08 g
(or +325 mV) on the Y-axis, and +1.83 g (or +550 mV) on the
Z-axis. This ST pin can be left open-circuit or connected to
common (COM) in normal use.
Never expose the ST pin to voltages greater than VS + 0.3 V.
If this cannot be guaranteed due to the system design (for
instance, if there are multiple supply voltages), then a low
VF clamping diode between ST and VS is recommended.
DESIGN TRADE-OFFS FOR SELECTING FILTER
CHARACTERISTICS: THE NOISE/BW TRADE-OFF
The selected accelerometer bandwidth ultimately determines
the measurement resolution (smallest detectable acceleration).
Filtering can be used to lower the noise floor to improve the
resolution of the accelerometer. Resolution is dependent on
the analog filter bandwidth at XOUT, YOUT, and ZOUT.
The output of the ADXL335 has a typical bandwidth of greater
than 500 Hz. The user must filter the signal at this point to
limit aliasing errors. The analog bandwidth must be no more
than half the analog-to-digital sampling frequency to minimize
aliasing. The analog bandwidth can be further decreased to
reduce noise and improve resolution.
The ADXL335 noise has the characteristics of white Gaussian
noise, which contributes equally at all frequencies and is
described in terms of g/√Hz (the noise is proportional to the
square root of the accelerometer bandwidth). The user should
limit bandwidth to the lowest frequency needed by the applica-
tion to maximize the resolution and dynamic range of the
accelerometer.
With the single-pole, roll-off characteristic, the typical noise of
the ADXL335 is determined by
)1.6( ××= BWDensityNoiseNoiserms
It is often useful to know the peak value of the noise. 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.

USE WITH OPERATING VOLTAGES OTHER THAN 3 V
The ADXL335 is tested and specified at VS = 3 V; however, it
can be powered with VS as low as 1.8 V or as high as 3.6 V. Note
that some performance parameters change as the supply voltage
is varied.
The ADXL335 output is ratiometric, therefore, the output
sensitivity (or scale factor) varies proportionally to the
supply voltage. At VS = 3.6 V, the output sensitivity is typi-
cally 360 mV/g. At VS = 2 V, the output sensitivity is typically
195 mV/g.
The zero g bias output is also ratiometric, thus the zero g
output is nominally equal to VS/2 at all supply voltages.
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 = 3.6 V,
the X-axis and Y-axis noise density is typically 120 µg/√Hz,
whereas at VS = 2 V, the X-axis and Y-axis noise density is
typically 270 g/√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, the self-test response in volts
is roughly proportional to the cube of the supply voltage. For
example, at VS = 3.6 V, the self-test response for the ADXL335
is approximately −560 mV for the X-axis, +560 mV for the
Y-axis, and +950 mV for the Z-axis.
At VS = 2 V, the self-test response is approximately −96 mV for
the X-axis, +96 mV for the Y-axis, and −163 mV for the Z-axis.
The supply current decreases as the supply voltage decreases.
Typical current consumption at VS = 3.6 V is 375 µA, and typi-
cal current consumption at VS = 2 V is 200 µA.
