I'd like to know the type of the totem-pole output of the DB0 to the DB11 pins.
Both high and low sides of the totem-pole are used FET or transistor? Is there a resistor on the high side line?
If you have the equivalent circuit of the totem-pole, please send it to me.
I estimate how the AD7472 works if the short circuit between DBx and DBx+1 occured.
I am sorry but this data is an ADI property. An equivalent circuit could be Ibis models but unfortunately, we do not have ibis model for AD7472. There are several ADC were Ibis models are available like AD4000, AD7606 to name a few. You can refer to the link.
