Dear Sir/Madam,


I just got the 3 questions for your AD5700/AD5700-1 good HART device from our customer.



As for some pins AD5700 and AD5700-1, do you have the power come on/off sequence?

Otherwise what is the better sequence?

I think that the RESET pin should be L to H at very last, correct?



After the power come on, does AD5700/5700-1 send out any data from "HART OUT"pin soon?

I think that if the RESET pin is pulled to L, any data doesnt appear the HART OUT pin,correct?



When can we start to communicate Tx/Rx HART after power come on and RESET pin L to H?

On your datasheet page-11 figures, I could not catch well.


Thanks Kaos
