Hi support team.

I have been asked by my customer  that how to calculate and measure PSRR.

Could you provide the information that how to calculate or measure PSRR.

My customer is thinking about how to calculate below, is it correct?

PSRR = 20log(Vin_niise_rms / Vout_noise_rms) 

Vout_noise_rms is PGA output noise.

Could you please tell me regarding above question?

Best regards,

Higa
