GENERAL DESCRIPTION
The ADXL204 is a high precision, low power, complete dualaxis 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). The typical noise floor is 170 g/Hz, allowing signals below 2 mg (0.1 of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<60 Hz). 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. The ADXL204 is available in a 5 mm x 5 mm x 2 mm, 8-terminal hermetic LCC package.

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.

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. 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. The output of the demodulator is amplified and brought offchip through a 32 k 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 nonmonotonic behavior, and temperature hysteresis is very low, typically less than 10 mg over the -40C to +125C temperature range. Figure 10 shows the zero g output performance of eight parts (X-axis and Y-axis) over a -40C to +125C temperature range. Figure 13 demonstrates the typical sensitivity shift over temperature for VS = 3.3 V. Sensitivity stability is typically better than 1% over temperature.

ADXL204 APPLICATIONS
POWER SUPPLY DECOUPLING
For most applications, a single 0.1 F 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 , or smaller, resistor or ferrite bead can be inserted in the supply line of the ADXL204. Additionally, a larger bulk bypass capacitor, in the 1 F to 22 F range, can be added in parallel to CDC.
DESIGN TRADE-OFFS FOR SELECTING FILTER CHARACTERISTICS: THE NOISE/BW TRADE-OFF
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. The ADXL204 noise has the characteristics of white Gaussian noise, which contributes equally at all frequencies and is described in terms of g/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. With the single-pole, roll-off characteristic, the typical noise of the ADXL204 is determined by rmsNoise = (170 g/Hz) x (BWx1.6) At 100 Hz the noise is rmsNoise = (170 g/Hz) x (BWx1.6) = 2.15 mg 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. Table 7. Estimation of Peak-to-Peak Noise
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 F-3 dB = 1/(2(32 k) x C(X, Y)) or more simply, F-3 dB = 5 F/C(X, Y) The tolerance of the internal resistor (RFILT) can vary typically as much as 25% of its nominal value (32 k); thus, the bandwidth varies accordingly. A minimum capacitance of 2000 pF for CX and CY is required in all cases. Table 6. Filter Capacitor Selection, CX and CY
Bandwidth (Hz) 1 10 50 100 200 500 Capacitor (F) 4.7 0.47 0.10 0.05 0.027 0.01
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 accelerometer. 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 VS + 0.3 V. If the system design is such that this condition cannot be guaranteed (that is, multiple supply voltages present), a low VF clamping diode between ST and VS is recommended.

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. 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
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. 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. The zero g bias output is also ratiometric, so 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 V, the noise density is typically 190 g/Hz. At VS = 5 V, the noise density is typically 110 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, 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 A.
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 is converted to an acceleration that varies between -1 g and +1 g, the output tilt in degrees is calculated as: PITCH = ASIN(AX/1 g) ROLL = ASIN(AY/1 g) 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.
