Hi, 

Is there a PSRR vs Frequency diagram for TL082 & TL072?

Thanks.

Zhou

  • Hello Zhou,

    This information is not included in the TL072 or TL082 product datasheets. We are looking to see if this data has been measured already and will reply back based on what we find.

    Hi Collin,

    Thanks. We require PSRR for power ripple impact analysis.

    Thanks a lot.

    Zhuo,

    Sorry, I was unable to find this data.

    I could guess at it. AVD is typically 106db (200V/mV) and KSVR is typically 100 dB, and B1 bandwidth is 3MHz

    Assuming same dominant pole location, PSRR zeros out at 1.5 MHz (3MHz/ (106dB-100db))

    I estimate PSRR to look like this.
