C | Page 9 of 14 ADXL316 Data Sheet THEORY OF OPERATION The ADXL316 is a complete 3-axis acceleration measurement system. The ADXL316 has a measurement range of 16 g minimum. It contains a polysilicon surface micromachined sensor and signal conditioning circuitry to implement an openloop 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 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 moving mass and unbalances the differential capacitor, resulting in a sensor output with an amplitude proportional to acceleration. Phase-sensitive demodulation techniques determine the magnitude and direction of the acceleration. A 32 k resistor can amplify and bring the demodulator output off-chip. 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 ADXL316 uses a single structure for sensing the X-, Y-, and Z-axes. As a result, the three axes sense directions are highly orthogonal with minimal cross axis sensitivity. Mechanical misalignment of the sensor die to the package is the chief source of cross axis sensitivity. Mechanical misalignment can be calibrated out at the system level. PERFORMANCE Rather than using additional temperature compensation circuitry, innovative design techniques ensure high performance is built in to the ADXL316. As a result, there is neither quantization error nor nonmonotonic behavior, and temperature hysteresis is very low. Rev. C | Page 10 of 14 Data Sheet ADXL316 APPLICATIONS INFORMATION POWER SUPPLY DECOUPLING SELF TEST For most applications, a single 0.1 F capacitor, CDC, placed close to the ADXL316 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 (or smaller) resistor or a ferrite bead can be inserted in the supply line. Additionally, a larger bulk bypass capacitor (1 F or greater) can be added in parallel to CDC. Ensure that the connection from the ADXL316 ground to the power supply ground is low impedance, because noise transmitted through ground has a similar effect as noise transmitted through VS. The ST pin controls the self test feature. When this pin is connected 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 -0.88 g (corresponding to -50 mV) on the x-axis, 0.88 g (or +50 mV) on the y-axis, and 1.58 g (or +90 mV) on the z-axis. The ST pin may be left open circuit or connected to the common pin (COM) in normal use. SETTING THE BANDWIDTH USING CX, CY, AND CZ The ADXL316 has provisions for band-limiting the XOUT, YOUT, and ZOUT 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, Z)) or more simply f-3 dB = 5 F/C(X, Y, Z) The tolerance of the internal resistor (RFILT) can vary by as much as 15% of its nominal value (32 k), and the bandwidth varies accordingly. A minimum capacitance of 0.0047 F for CX, CY, and CZ is recommended in all cases. Table 4. Filter Capacitor Selection, CX, CY, and CZ Bandwidth (Hz) 1 10 50 100 200 500 Capacitor (F) 4.7 0.47 0.10 0.05 0.027 0.01 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), 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 (the smallest detectable acceleration). Filtering can 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 ADXL316 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 decrease further to reduce noise and improve resolution. The ADXL316 has 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). 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 rms noise of the ADXL316 is determined by RMS Noise = Noise Density x ( BW x 1.6 ) Often, the peak value of the noise is desired. Statistical methods can only estimate peak-to-peak noise. Table 5 is useful for estimating the probabilities of exceeding various peak values, given the rms value. Table 5. Estimation of Peak-to-Peak Noise Peak-to-Peak Value 2 x rms 4 x rms 6 x rms 8 x rms Rev. C | Page 11 of 14 % of Time that Noise Exceeds Nominal Peak-to-Peak Value 32 4.6 0.27 0.006 ADXL316 Data Sheet USE WITH OPERATING VOLTAGES OTHER THAN 3 V The supply current decreases as the supply voltage decreases. Typical current consumption at VS = 3.6 V is 400 A, and typical current consumption at VS = 2 V is 300 A. The ADXL316 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. AXES OF ACCELERATION SENSITIVITY Figure 22 shows the axes of acceleration (AX, AY, and AZ) sensitivity, corresponding output voltage increases when accelerated along the sensitive axis. The ADXL316 outputs are ratiometric, so the output sensitivity (or scale factor) is proportional to the supply voltage. At VS = 3.6 V, the output sensitivity is typically 78 mV/g. At VS = 2 V, the output sensitivity is typically 42 mV/g. AZ The zero g bias output is also ratiometric, so the zero g output is nominally equal to VS/2 at all supply voltages. 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 ADXL316 is approximately -86 mV for the x-axis, +86 mV for the y-axis, and +162 mV for the z-axis. At VS = 2 V, the self test response is approximately -14 mV for the x-axis, +14 mV for the y-axis, and +28 mV for the z-axis. AX Figure 22.

This decrease 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 150 g/Hz, while at VS = 2 V, the x-axis and y-axis noise density is typically 280 g/Hz.
