... The CS4340A accepts data at all standard audio sample rates up to 192 kHz, consumes very little power, oper- ates over a wide power supply range and is pin compatible with the CS4340, as described in section 3.1. These features are ideal for DVD audio players. ORDERING INFORMATION CS4340A-KS CDB4340A DEM MUTEC External De-emphasis ...

... The CS4340A is pin and functionally compatible with all CS4340 designs, operating at the standard audio sample rates, that use pin serial clock input. In addition to the features of the CS4340, the CS4340A supports standard sample rates up to 192 kHz, as well as automatic mode detection for sample rates be- tween 4 and 200 kHz ...

... Popguard Transient Control ® The CS4340A uses Popguard and power-down. This technology, when used with external DC-blocking capacitors in series with the au- dio 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 CS4340A requires careful attention to power supply and grounding arrangements if its potential performance realized. Figure 1 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 & ...
