Hello,

in the datasheet of AD9781 it is given that it requires a positive pulse for getting reset. but after power on if the reset pin is kept high for 1us or more and after 10ns SPI is programmed then this chip will work or not ?

the waveform at the reset pin after power on is like this

is this sufficient to get the DAC out of reset or after keeping this pin high after the power on then we need to make it low and then again provide a pulse ?

 

Thanks and Regards,

Nikhil
