Product Number: AD7791

The actual test power consumption of the AD7791 power failure mode is about 30uA, which does not meet the 1uA current described in the manual. Please help inform us how to achieve this, thank you

Hi AaronSu ,

The data described on the datasheet is tested with these conditions: VDD = 2.5 V to 5.25 V; REFIN(+) = 2.5 V; REFIN(–) = GND; GND = 0 V; CDIV1 = CDIV0 = 0 as stated on the table 1 of the datasheet; can you confirm this on your setup?

Thanks and regards,

Rod
