10.13.2 DC interface to an Analog Quadrature Modulator (AQM)
When the system operation requires to keep the DC component of the spectrum, the
DAC1008D750 must use a DC interface to connect to an AQM. In this case, the offset
compensation for LO cancellation can be made with the use of the digital offset control in
the DAC.

The auxiliary DACs can be used to control the offset in a precise range or with precise
steps.
