How much is the internal delay when I input a pulse?
I think that a delay produces 30ns in an ISO part.How many will the quantity of delay in the ADC circuit part be?
We are looking into this and get back to you.
I am confirming some data with the product line. I'll get back to you.
The AD7400A is Sigma Delta modulator. The clock is internally generated and will drive the modulator. Then both clock and modulator MDAT signal are transferred across the isolation and appear at the microcontroller at the same time. The delay to cross this is very minimal. The AD7400A is a Sigma Delta modulator and requires filter which will add majority of the delay.
