converted to an output voltage proportional to the acceleration on that axis.

Ratiometric Output

Ratiometric output means that the output voltage increases linearly with acceleration over the

range.

For the ADXL335, that is approximately 0v at -3G to 3.3v at +3G.

For the ADXL326, that is approximately 0v at -16G to 3.3v at +16G.

For the ADXL377, that is approximately 0v at -200G to 3.3v at +200G.

For all modules, the output at 0G in each axis, is about 1/2 full-scale, or 1.65v.

Note that the specified device ranges are guaranteed minimum ranges.

Most actual

devices will have a somewhat wider usable range.

Also, due to manufacturing

variations the zero point may be slightly offset from exactly 1/2 scale.

We will

discuss how to calibrate the range and offset in the Calibration and Programming

section of this guide.
