GENERAL DESCRIPTION
The ADXL316 is a small, thin, low power, complete 3-axis
accelerometer with signal conditioned voltage outputs. The
product measures acceleration with a minimum measurement
range of ±16 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 ADXL316 is available in a small, low profile, 4 mm × 4 mm ×
1.45 mm, 12-lead, plastic lead frame chip scale package (LFCSP).

1 Guaranteed by measurement of initial offset and sensitivity.
2 Sensitivity is essentially ratiometric to VS. Calculate sensitivity by using a scale factor (mV/V/g). Sensitivity = Scale Factor × VS. To calculate minimum and maximum
sensitivity, the scale factors are 15 mV/V/g and 23 mV/V/g, respectively.
3 This parameter is defined as the output change from ambient to maximum temperature or ambient to minimum temperature.
4 Actual frequency response controlled by user-supplied external filter capacitors (CX, CY, and CZ).
5 Bandwidth = 1/(2 × π × 32 kΩ × C). For CX, CY = 0.003 μF, the bandwidth = 1.6 kHz. For CZ = 0.01 μF, the bandwidth = 500 Hz. For CX, CY, and CZ = 10 μF, the bandwidth = 0.5 Hz.
6 Self test response changes cubically with VS.
7 Larger values of CX, CY, and CZ increase turn-on time. Turn-on time is approximately 160 × (CX, CY, and CZ) + 4 ms, where CX, CY, CZ are in μF.
