Other Parts Discussed in Thread: ADS58H40, ADS58H43
ADS4449 appears to be an excellent option for my application. I am interested in performing sampling at baseband (Fc = 0 Hz) with a lowpass filter as opposed to an offset IF with a bandpass filter as described in the data sheet.
Q1: Are there any limitations with the device, such as an inherent highpass behavior in the converters, that would might make baseband sampling challenging?
Q2: Is there a data sheet for another high speed converter that I might look to for a baseband buffer circuit?
Also, the ADS4449, ADS58H40 and ADS58H43 appear to be almost identical. I'm curious to know what the real differences are between these devices, which might not be obvious via the comparison tool, and which is likely to be furthest from end-of-life.
Many Thanks,
David
