... Popguard Transient Control ® The CS4340 uses Popguard technology to minimize the effects of output transients during power-up and power- down. This technology, when used with external DC-blocking capacitors in series with the audio outputs, minimizes the audio transients commonly produced by single-ended single-supply converters activated inside the DAC when RST is enabled/disabled and requires no other external control, aside from choosing the appropriate DC- blocking capacitors ...

... Grounding and Power Supply Arrangements As with any high resolution converter, the CS4340 requires careful attention to power supply and grounding arrange- ments if its potential performance realized. Figure 14 shows the recommended power arrangements, with VA connected to a clean supply. If the ground planes are split between digital ground and analog ground, REF_GND & ...
