Info kindly requested on the UcD 400 schematic.

Dear Friends,

I am figuring out the actual schematic of the UcD 400 module.
I know there is an op-amp at the input follow by a "modulator" or something like that that then drives the output devices?
I have the following doubt: is the op-amp providing all the voltage gain or is a buffer?
I wonder if it could be possible to drive the modulator directly for single ended operation by-passing the input op-amp.
Thank you to everyone will redirect me to some useful links about the real schematic.

Kind regards,

beppe

Thanks again Mr Chris.
I will study the application note in the hope of understanding better the working principle.
Kind regards,
