Part Number: LMH6624
Tool/software: TINA-TI or Spice Models
I have a little problem with simulating the LMH6624. I would like to use this device for an Butterworth filtter 4th order. The max frequency i want to work with is 1Mhz.
None of my tried applications seems to work so i've broke it down to the beginning and tried some standard non inverting circuit.
The input Voltage is 100mV on 1Mhz.
Why is the simulation going into something like a saturation, vice versa the voltage follower seems to work.. Did i miss something? I have no clue where my mistake could be =( .
I appreciate any help.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Stefan Langlouis:
if you use a single supply voltage, you must take care that the DC operating point is not amplified by the signal gain. So, you urgently need a high pass in the feedback loop, here introduced by C2:
