Hi, I'm using the 12VDC SMPS to power the REF02A 5V Precision Voltage Reference.
I'm not sure what impact the SMPS will have on the output of the REF02A. Can anyone advise me on this topic?
In general switchers can be noisy, so I'd say filter the output of the switcher to clean it up before bringing it into the REF02.
I'm going to move this into the Amplifier community in case there is more information from someone there.
