Note Regarding Extended Mode Offset Correction
When using the I or Q channel Offset Adjust registers, the following information should be noted.
For offset values of +0000 0000 and -0000 0000, the actual offset is not the same. By changing only the sign bit
in this case, an offset step in the digital output code of about 1/10th of an LSB is experienced. This is shown
more clearly in Figure 10 below.
