AD8638 - is it possible to bootstrap the power rails to decrease Cin common mode?

Hi,

I don't think bootstrapping, as per Issue 168, is the answer to decrease the input common-mode capacitance of the amplifier. Do you have a circuit that I could take a look?

The AD8638 already has one of the lowest input common-mode capacitance in our zero-drift amplifier portfolio. What input common-mode capacitance do you have in mind?

Thanks,

Donnie

Hi Donnie,

Is it possible discuss by email.  The project is proprietary.

Hi John,

Apologies for the late response. Yes, I already sent you an email using the one registered in your engineer zone account.

Thanks,

Donnie
