Hi Brad,

Thanks for your interest in the LMV651.

Would you provide me more details about the signal you're trying to drive while I look into the input impedance of this device?

Regards,

-Mamadou

Hi Brad,

LMV651 input impedance will be roughly 3pF differential and 5pF common-mode based on devices of similar architecture. The 80nA input bias current will dominate any input resistance effects.
