Hello,
Can anyone give me any ideas why my LTC6260-based MFG bandpass filter is oscillating at ~3.3MHz? The LTSpice file is attached, and doesn't show any signs of oscillation.
Thanks,
Evan

Hi,
I have a few questions
Do you have the actual scope shot or waveform of the oscillation you are seeing at 3.3MHz?
What is the frequency range of the bandpass filter?
What is your intended application?
Hello,
I discovered the cause; it was a 3.28MHz clock signal that was coupling into the filter output trace (which is rather long). The final application won't have this clock active during the time that the filter output is important.
Thanks,
Evan
