Preliminary data
9.1.3 Coarse and Fine registers
Table 5:
The default programmed value is:
These two registers enable the gain control, the AGC gain with the coarse register
and the reference voltage with the fine register. The coarse register programming
equation is as follows:
Where: V
The gain correspondence is given in
