TPS7B4250-Q1: PSRR Data sheet graph

Antenna_Head

Genius 11375 points

Part Number: TPS7B4250-Q1

Figure 11 of the data sheet seems to indicate PSRR performance of > 90 dB out past 1 MHz, see below.

This seems extremely optimistic. Is this really true?

Hey Steve,

I agree it does look very optimistic. Let me run a measurement. I'll have results by Friday.

This seems more reasonable.

Any plans to update what's found in the data sheet?

Thanks!

Best, Steve

Hey Steve,

Yes, this is on our backlog. We'll be sure to correct this plot as part of that revision.
