AD9467 minimum analog input frequency

Hi there,

We are feeding IF signals of frequency 5-20 KHz to AD9467 at less than 150MSPS Sampling rate. Will ADC accepts this input range?

But in datasheet, buffer current characteristics is given as follows(PFA). I can find delay line, it is not starting from DC.Can you please clarify on this.

Thanks in Advance

    Yes. You will need to use an amplifier and DC couple to the ADC. the datasheet numbers are taken from the circuit shown in figure 51 of the datasheet. the transformers dont work well up to DC. You will need a DC coupled network using an amplifier like the ADA4930-1. You can use the amplifier to convert the signal from a single ended one to differential one too.
