Tool/software:
This question is not specific to the PGA855 - I just had to put a part number in that field. I'm looking for a variable gain amplifier, differential in, differential or single-ended out. Would prefer single supply (+5V), but will embrace dual supplies if necessary. Gain has to be 0-20 dB nominally, more is OK but gain control could limit it. Having some attentuation and some gain would be good as well. BW <100Mhz, could even be as low as 10 MHz. Gain control could be analog, or digital provided it has some granularity. Here is the kicker making this hard: Needs to be DC-coupled - most are only AC-coupled or targeted at RF/IF applications. Anything out there I could use?
