DELTA VELOCITY
The delta velocity outputs represent an integration of the
accelerometer measurements and use the following formula
for all three axes (x-axis displayed):
where:
a
Δt
When using the internal sample clock, f
When using the external clock option, the time between samples
is the time between active edges on the input clock signal, as
measured by the internal clock (252 MHz). See Table 67 for
more information on the DEC_RATE register. The registers
that use the x_DELTVEL_OUT format are the primary registers
for the delta velocity calculations. When processing data from
these registers, use a 16-bit, twos complement data format (see
Table 31, Table 32, and Table 33). Table 34 provides
x_DELTVEL_OUT digital coding examples.
