I've read the specification in search of the power on reset state for this DAC: I've either missed this detail or its not defined. Can someone check documentation to see if the power on state is defined?
The AD5543 do not have a power on reset circuitry.
We experience some issues with this component.
The power on reset behavior is not described in the datasheet and according to our tests, the AD5543 is in full scale state at power up.
This behavior is unacceptable from our point of view (we use the AD5543 in a regulation loop).
The datasheet of the AD5543 could be updated.
