Thanks, Kleinstein and Terry, for your continued help and support!
It has been pointed out several times that I must state very specific needs/uses, in order to be able to select a particular all-in-one chip. I have supplied the details that I know. Admittedly, that information has been insufficient. I just don't have that knowledge base... yet. All I can say is that I don't generally work with super-high frequencies. I work with the typical MCU oscillator frequencies, and maybe, someday, I will advance to the transmission frequencies for Blue Tooth and WiFi, in support of the MCUs. As for all the perimeters that are a trade-off, one for the other, I would say to split the difference in performance. I do know that I would uses it for various sensors - such as a strain gauge, or an earthquake sensor.
I intend to continue to work/learn/have fun, within the subject, by breadboarding the 3-OA design that I mentioned earlier. See LT1002 Data Sheet/Pg 10. I will substitute the op amps that I have in stock... TL081s for the LT1002s and a LM741 for the LT1037. If it fails, I will learn why. If it succeeds, I will add the additional suggested tweaks.
I had asked about using split supply - the advantage/disadvantages. I still need those details, please. I understand the battery power considerations.
