... MSPS. At internal clock rates below 1 MSPS, dynamic perfor- mance may degrade. Therefore, input clock rates below 1 MHz should be avoided. During initial power-up, or whenever the clock to the AD9432 is interrupted, the output data will not be accurate for 200 clock cycles, whichever is longer. ...

... USING THE AD8138 TO DRIVE THE AD9432 The AD8138 differential output op amp can be used to drive the AD9432 in dc-coupled applications. The AD8138 was specifically designed for ADC driver applications. Superior SNR performance is maintained up to analog frequencies of 30 MHz. The AD8138 op amp provides single-ended-to-differential conversion, which allows for a low cost alternative to transformer coupling for ac applications, as well ...
