    Hi,
    

    I am using the AD8367 amplifier in VGA mode and it is oscillating at high gain settings. Looking at the datasheet and in particular the HPFL and DECL pins, I was wondering if I can modify the feedback network using these pins to sacrifice some gain for stability. Please let me know if you have any ideas.
    

    Thank you,
