AD9814  
APPLICATIONS INFORMATION  
Circuit and Layout Recommendations  
should occur coincident with or before the rising edge of  
ADCCLK (see Figures 1 through 4 for timing). All 0.1 µF  
decoupling capacitors should be located as close as possible to  
the AD9814 pins. When operating in single channel mode, the  
unused analog inputs should be grounded.  
The recommended circuit configuration for 3-Channel CDS  
mode operation is shown in Figure 15. The recommended input  
coupling capacitor value is 0.1 µF (see Circuit Operation section  
for more details). A single ground plane is recommended for the  
AD9814. A separate power supply may be used for DRVDD,  
the digital driver supply, but this supply pin should still be  
decoupled to the same ground plane as the rest of the AD9814.  
The loading of the digital outputs should be minimized, either  
by using short traces to the digital ASIC, or by using external  
digital buffers. To minimize the effect of digital transients during  
major output code transitions, the falling edge of CDSCLK2  
Figure 16 shows the recommended circuit configuration for 3-  
Channel SHA mode. All of the above considerations also apply  
for this configuration, except that the analog input signals are  
directly connected to the AD9814 without the use of coupling  
capacitors. The analog input signals must already be dc-biased  
between 0 V and 4 V (see the Circuit Operation section for  
more details).
