ADS1675: PSRR AC and DC data available?

AnBer

Part Number: ADS1675

Team,

Looking at the datasheet we do not provide PSRR specification. There are some power supply design advises provided at page 28 of SBAS416D but it is quite succint
Do we have PSRR AC and DC data to share?
Do we have PSRR data vs frequency to share?

I have looked at the below video already:

Thanks in advance,

Hello A.

I doubt we have any additional information to share, but I will see what I can find. Please give me until Friday to get back.

Hi Anthony,

I searched through all of the archived data and could not find any PSRR information. Best estimate would be around 80dB at 50/60Hz, based on other similar devices.

If I later find something, I will forward it to you, but at this point, I think the measurements would need to be made.

Regards,
Keith
