Question
We use the AD5235s in a very sensitive RFI environment. On system power-on, howis the scratchpad register refreshed with the EEMEM value? Is it clocked in?
Answer
At power up, the internal oscillator turns on, waits for power up time ofinternal NVM and then it loads NVM value to internal register.So yes, the clock is used to load the NVM value to scratchpad register.Internal Frequency is 1MHz, and it switches off after registers are loaded.
