Hello, help me please! I use DAC AD1852 and digital potenciometer AD5262. I need to disable analog power these chips, but digital power is always enabled. Can it damage AD1852 or AD5262?
How long do you need to disable the analog supplies from these chips?
For the AD5262, the ideal power-up sequence is in the following order: GND, VDD, VSS, VL, the digital inputs, and VA/VB/VW. Although turning the digital supply on while the analog supplies are off should be fine.
For the AD1852, there seems to be no power supply sequence requirement so i think that will be fine.
