REV. 0
to that provided by the converter and preamp (if used). It is
necessary to use sufficient post filtering with the accelerometer
to reduce its noise floor to allow full use of the converter’s reso-
lution (see post filtering section).
The use of a gain stage following the accelerometer will nor-
mally require the user to adjust the zero
g
offset level (either by
trimming or by resistor selection—see previous sections).
For many applications, a modern “economy priced” 10-bit
converter, such as the AD7810 allows you to have high resolu-
tion without using a preamp or adding much to the overall
circuit cost. In addition to simplicity and cost, it also meets two
other necessary requirements: it operates from a single +5 V
supply and is very low power.
