ADMV1013 BLOCK DIAGRAM AND FUNCTIONS
The ADMV1013 plugin appears similar to the block diagram
shown in the ADMV1013 data sheet. The similarities between
the plugin and the block diagram make it easy to correlate the
functions on the ADMV1013-EVALZ evaluation board with the
corresponding descriptions in the
ADMV1013 data sheet. The
ADMV1013 data sheet provides a full description of each block
and register, as well as the corresponding settings. Some blocks
and functions pertain to the ADMV1013-EVALZ evaluation board.
Figure 14 shows the full screen
ADMV1013 block diagram with
labels, and Table 1 describes the functionality of each block.
