Figure 26. Connecting the Reference Ground
Channel-to-channel dc crosstalk is a major concern in multichannel applications, such as battery test equipment.
While the DACx1001 is single-channel, the crosstalk problem can appear at a system level when using multiple
DACx1001 devices. The problem becomes severe when the grounds of the loads are shorted together creating a
possible ground loop. In such cases, avoid the local short between AGND and AGND-OUT. Use a single short
between AGND and DGND for all the DACs. If the PCB layout allows for the digital signal and analog power
supplies to be kept separate, DGND and AGND can be combined to a single ground plane. Figure 27 shows an
example circuit for minimizing dc crosstalk across DAC channels in a system.
