down state is related to the value of the DC-blocking capacitance. For example, with a 3.3 µF capacitor, the
time that the device must remain in the power-down state will be approximately 0.4 seconds.
Grounding and Power Supply Decoupling
As with any high resolution converter, the CS4334 family requires careful attention to power supply and
grounding arrangements to optimize performance. Figure
with VA connected to a clean +5V supply. For best performance, decoupling capacitors should be located
as close to the device package as possible with the smallest capacitor closest.
Analog Output and Filtering
The analog filter present in the CS4334 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
