... The FILT+ and VQ decoupling capacitors, particularly the 0.1 µF, must be positioned to minimize the electrical path from FILT+ and REF_GND (as well as VQ and REF_GND), and should also be located on the same layer as the DAC. The CDB4340A evaluation board demonstrates the optimum layout and power supply arrangements. ...
