Coudl you teach me about the output logic level when the VDD1 of AD740x is off ?
VDD1 supply rarely off at fault condition of power circuit in our customer's circuit.
AD7400 and AD7401 datasheet P.1 says that these devices include watchdog.
So, I think that AD7400 and AD7401 output high or low when VDD1 is off.
Is it correctt ?
Regarding to question1 , does AD7402 and AD7403 have the same function ?
Regarding to 1 , could you teach me about the period of watchdog ?
