Hi jgirgis: The low frequency performance is dictated by the hold capacitor and the bleeder resistor, C2 and R14. (Or, in the linked LTC6244 circuit, C1 and R4.)
About the "Improved Peak Detector" available here:

For the peak detector circuit, we have the ADA4622 which is optimized for this type of applications. You can take advantage of the dc precision and super low bias current to get a highly accurate circuit. It also has a sample circuit discussion…
Hi,I'm trying to simulate the following circuit and can't get it to work in LTSpice without 1.2 MHz oscillations. What could I do to make the simulation work as expected?
The circuit is from page 19 of the LTC6244 datasheet.Thanks
Here's my LTspice…
Thanks a lot for the solution. I'll certainly try out the second circuit which looks easy with minimal components.
Could you please take a look at the attached datasheet of LTC6244, page 21?
It explains FDA from single ended opamps. I'm…
Hi,Usually due to fabrication process, slew rate could vary +20% from it's typical value. So for ADA4665 this could range from 0.8V/μs up to 1.2V/μs. But some other parts could go up to +50% like LTC6244.May I know why you needed the value and…
