... DAC output power requirements. When not in use, the ADA44330-1 can be shutdown to draw less than 1 μA of supply current using the power-down pin Additionally, the ADA4430-1 is unique in that high order filter that fits into an SC70 package. The ADA4430-1 provides a minimum 1 dB bandwidth of 5 ...

... The ADA4430-1 is ideally suited for use as a reconstruction filter that follows a video DAC or encoder. The application circuits in Figure 29, Figure 30, and Figure 31 illustrate a number of ways the ADA4430-1 can be used with a single- supply current-output DAC on its input and its output ac- and dc-coupled. POWER-DOWN CONTROL ...
