DAC53701: DAC53701

Part Number: DAC53701

Good day!

I did not find an answer to the question:

after what time, after applying the supply voltage to the DAC53701, the output voltage will appear at its output. This means loading all registers from NVRAM.

Thank you.

Hi Vladimir,

Although the DAC has a POR of ~30ms, I have seen that the output goes to the NMV values much quicker than this. I though I had a plot showing the output startup time, but I cannot find it. Let me take another plot in the lab and I will post it here asap.

Best,

Thanks for your reply. For my project, I need the time after switching power on no more than 100 microseconds.

Hi Vladimir,

100us is definitely too fast.

I measured ~10ms in the lab after the supply reaches the minimum 1.8V.

What is your application that requires the 100us turn on time?

Thanks! Yes, I need time 100us after power is on. I make it with REF when power is on, after time delay 10 - 20 msec will start any regulations.

Best Regards
