Hi all,
I am using High speed op-amp for DAC board, is there any routing contraint(Say cutout ground plane beneath IC Input Pin). please suggest some some layout constraint for this.



Regards,
Arunmaran
 

Some high impedance inputs can be affected by the capacitance between the Pad and the ground plane (couples HF noise), but it is the minority, I second the recommendation to read the data sheets.
