Product data sheet
10.14.1 Basic output configuration
10.13 Auxiliary DACs
10.14 Output configuration
The DAC1405D750 integrates 2 auxiliary DACs that can be used to compensate for any
offset between the DAC and the next stage in the transmission path.
Both auxiliary DACs have a resolution of 10-bit and are current sources (referenced to
ground).
The output current depends on the auxiliary DAC data:
Table 42 “Auxiliary DAC transfer function”
auxiliary DAC data.
Table 42.
Default settings are shown highlighted.
The use of a differentially-coupled transformer output provides optimum distortion
performance (see
helps to match the impedance and provides electrical isolation.
