  • OPA387: Stability - lower Riso increases stability?

    Resolved
    Part Number: OPA387 Tying to fine-tune a simple amplifier based on on OPA387 I found out that the higher Riso resistor value the lower the stability - see the diagram below, phase-margin(Aol)=61.5°@Riso=100Ω. When Riso is 51 Ω, phase-margin (Aol…

  • RE: OPA376: OPA376 issue in high temperature

    Resolved
    HI Nathan, We discussed the issue on the OPA376. The datasheet shows the CMRR changes from 90dB @25C to 60dB @150C, at hot temperature, where CMRR is specified above V(-) supply. The datasheet offers no assurances for CMRR for voltage more negative than…
