AC interface to an Analog Quadrature Modulator (AQM)
When the AQM common mode voltage is close to ground, the DAC1408D650 must be
AC-coupled and the auxiliary DACs are needed for offset correction.
Figure 25
is an example of an AC interface with the auxiliary DACs connected to an AQM
with a common-mode input level (V
i(cm)
) of 0.5 V.
