AC interface to an AQM
When the Analog Quadrature Modulator (AQM) common mode voltage is close to ground,
the DAC1205D650 must be AC-coupled and the auxiliary DACs are needed for offset
correction.
Figure 18
provides an example of a connection to an AQM with a 0.5 V common mode
input level using auxiliary DACs.
