The ADXL103/ ADXL203 measure acceleration with a full-scale range of ±1.7 _g_ , ±5 _g_ , or ±18 _g_ . The ADXL103/ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity). The typical noise floor is 110 μ _g_ /√Hz, allowing signals below 1 m _g_ (0.06° 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 ADXL103 and ADXL203 are available in a 5 mm × 5 mm × 2 mm, 8-terminal ceramic LCC package. ## **FUNCTIONAL BLOCK DIAGRAMS** **==> picture [461 x 152] intentionally omitted <==** **----- Start of picture text -----**<br> +5V +5V<br>VS VS<br>ADXL103 ADXL203<br>CDC AC DEMOD OUTPUT CDC AC DEMOD OUTPUT OUTPUT<br>AMP AMP AMP AMP AMP<br>SENSOR SENSOR<br>RFILT RFILT RFILT<br>32kΩ 32kΩ 32kΩ<br>COM ST XOUT COM ST YOUT XOUT<br>CX CY CX<br>Figure 1.<br>03757-001<br>**----- End of picture text -----**<br> **Document Feedback** **Rev.

F | Page 12 of 16 **Data Sheet** **ADXL103/ADXL203** ## **THEORY OF OPERATION** The ADXL103/ADXL203 are complete acceleration measurement systems on a single, monolithic IC. The ADXL103 is a singleaxis accelerometer, and the ADXL203 is a dual-axis accelerometer. Both devices contain 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 ADXL103/ADXL203 are capable of measuring both positive and negative accelerations from ±1.7 _g_ to at least ±18 _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 then rectify the signal and determine the direction of the acceleration. 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 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 m _g_ over the −40°C to +125°C temperature range). Figure 11 shows the 0 _g_ output performance of eight devices (x and y axes) over a −40°C to +125°C temperature range. Figure 13 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 ±1% over temperature at VS = 3 V. **==> picture [237 x 191] intentionally omitted <==** **----- Start of picture text -----**<br> PIN 8<br>XOUT = –1 g<br>YOUT = 0 g<br>PIN 8 TOP VIEW PIN 8<br>XOUT = 0 g (Not to Scale) XOUT = 0 g<br>YOUT = +1 g YOUT = –1 g<br>XOUT = 0 g<br>YOUT = 0 g<br>PIN 8<br>XOUT = +1 g<br>YOUT = 0 g<br>EARTH’S SURFACE<br>03757-028<br>**----- End of picture text -----**<br> _Figure 39. Output Response vs. Orientation_ Rev. F | Page 13 of 16 **Data Sheet** ## **ADXL103/ADXL203** ## **APPLICATIONS INFORMATION 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 can cause interference on the ADXL103/ ADXL203 output. If additional decoupling is needed, a 100 Ω (or smaller) resistor or ferrite beads can be inserted in the supply line of the ADXL103/ADXL203. Additionally, a larger bulk bypass capacitor (in the 1 µF to 22 µF range) can be added in parallel to CDC. ## **SETTING THE BANDWIDTH USING CX AND CY** The ADXL103/ADXL203 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 _f_ –3 _dB_ = 1/(2π(32 kΩ) × _C_ ( _X_ , _Y_ )) or more simply, _f_ –3 _dB_ = 5 µF/ _C_ ( _X_ , _Y_ ) The tolerance of the internal resistor (RFILT) can vary typically as much as ±25% of its nominal value (32 kΩ); thus, the bandwidth varies accordingly. A minimum capacitance of 2000 pF for CX and CY is required in all cases. ## **DESIGN TRADE-OFFS FOR SELECTING FILTER CHARACTERISTICS: THE NOISE/BANDWIDTH TRADE-OFF** The accelerometer bandwidth selected ultimately determines the measurement resolution (smallest detectable acceleration). Filtering can lower the noise floor, improving 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 analog-to-digital sampling frequency to minimize aliasing. The analog bandwidth can be further decreased to reduce noise and improve resolution. The ADXL103/ADXL203 noise has the characteristics of white Gaussian noise, which contributes equally at all frequencies and is described in terms of µ _g_ /√Hz (that is, the noise is proportional to the square root of the accelerometer bandwidth). 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 ADXL103/ADXL203 is determined by _rmsNoise_ = (110 µ _g_ /√Hz) × ( BW × 6.1 At 100 Hz, the noise is **Table 7. Filter Capacitor Selection, CX and CY** |**Bandwidth (Hz)**|**Capacitor (µF)**| |---|---| |1<br>10<br>50<br>100<br>200<br>500|4.7<br>0.47<br>0.10<br>0.05<br>0.027<br>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 750 m _g_ (corresponding to 750 mV). This pin can be left opencircuit or connected to common in normal use. 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. _rmsNoise_ = (110 µ _g_ /√Hz) × ( 100 × 6.1 ) = 1.4 m _g_ Often, the peak value of the noise is desired. Peak-to-peak noise can only be estimated by statistical methods. Table 8 is useful for estimating the probabilities of exceeding various peak values, given the rms value. **Table 8. Estimation of Peak-to-Peak Noise** |**Peak-to-Peak Value**|**% of Time That Noise Exceeds**<br>**Nominal Peak-to-Peak Value**| |---|---| |2 × rms<br>4 × rms<br>6 × rms<br>8 × rms|32<br>4.6<br>0.27<br>0.006| Peak-to-peak noise values give the best estimate of the uncertainty in a single measurement; peak-to-peak noise is estimated by 6 × rms.

F | Page 14 of 16 **Data Sheet** **ADXL103/ADXL203** ## **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 change as the supply voltage is varied. The ADXL103/ADXL203 output is ratiometric, so the output sensitivity (or scale factor) varies proportionally to the 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. 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 μ _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. So at VS = 3 V, the self test response is approximately equivalent to 150 mV or equivalent to 270 m _g_ (typical). The supply current decreases as the supply voltage decreases. Typical current consumption at VDD = 3 V is 450 μA. ## **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, 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 m _g_ per degree of tilt. At 45°, its output changes at only 12.2 m _g_ per degree, and resolution declines. ## _**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. After 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. Rev.
