Hi,
Would you please provide us PSRR vs frequency data for OPA541 ?
Best Regards,
Kato

Hello Kato-san,
I searched our archieves and did not find any PSRR vs. frequency information for the OPA541, unfortunately. A "rough" approximation for most power op-amps is the positive PSRR tends to be similar to the CMRR curve, while the negative PSRR usually is lower by several tens of dB and has a lower break frequency.

Hello Kato-san,
The PSRR vs. frequency behavior is topology dependent. Since the OPA549 uses a very different internal topolgy from that used by the OPA541, there is no correlation.
