4.6 Grounding and Power Supply Decoupling

As with any high resolution converter, the CS4344 family requires careful attention to power supply and

grounding arrangements to optimize performance. Figure 6 shows the recommended power arrangement

with VA connected to a clean +3.3 V or +5 V supply. For best performance, decoupling and filter capacitors

should be located as close to the device package as possible with the smallest capacitors closest.

4.7 Analog Output and Filtering

The analog filter present in the CS4344 family is a switched-capacitor filter followed by a continuous time

low pass filter. Its response, combined with that of the digital interpolator, is given in Figures 13 - 20. The

recommended external analog circuitry is shown in the “Typical Connection Diagram” on page 11.
