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.
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.
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
