Hi Charles, Thank you very much for your reply! If I use +-48V for VPP and VNN, what is the best value of VSUB? The datasheet only say VSUB should <=VNN. And I see your reply that 'Yes, the output can overshoot more than 10% if you are connecting it to the transducer. When that happens, we recommend VSUB to be 10% (depending on the overshoot) lower than VNN." So VSUB should <=-52.8V. And is there a best value? Is VSUB=-65V the best value? Thank you so much! Frank
