Hi all,
A customer uses the DAC121C085. in their application scenario, the machine power will sometimes frequently power down and power up. then in some case, the part will work wrong. So as stated in datasheet, the power on reset have to make sure the Va raise from below than 200mV. it seems to be correlated.
so the customer question is:
1)how to avoid this power on reset failure or do we have some workaround?
2) do we have other DAC part don't need to make sure the correct power-on-reset must less than 200mV
