  • OPA277: OPA277 or LM741

    Resolved
    Part Number: OPA277 How would you test for this op amp's open loop output impedance vs frequency and dc physically? Are the inductor and capacitor there only for simulation or are small values needed in real life? And how would you apply a current…

  • RE: LM741: Operational Amplifier Failure

    Ron, Hope you had a good holiday and are having a good New Year. Thank you for the test setup and information! I will keep this in mind in the future if we get anymore failed units that we can get an IC from to test. Regarding the LM741CH, this is the…

  • LM741: Op-Amp Failure

    Part Number: LM741 I have encountered multiple failures of the LM741CH operational amplifier ICs. In operation, these ICs are configured for a voltage follower configuration as part of a most negative input voltage auctioneering circuit. The failures…

  • LM741: Differences between LM741 and LF356/TL071 with respect to high frequency noise.

    Part Number: LM741 Other Parts Discussed in Thread: LF356 , TL071 I am using the attached circuit. It is a standard inverting amplifier circuit. There is a class D switching amplifier nearby and the switching frequency is 51 kHz. Noise from the switching…

  • LM741-MIL: Military Grade clarification

    TI Thinks Resolved
    Part Number: LM741-MIL Other Parts Discussed in Thread: LM741QML Hi Guys, LM741-MIL Product page clearly specifies that it's a Military grade part, however need your confirmation if the rest of the OPN's specifically LM741J is a Military grade part as…

  • LM741: Spice- or Pspice-model of the opamp LM741

    Part Number: LM741 Hi Team I am searching for a pspice model of the LM741 with modeled offset-pins. In the circuit I have to rebuild in Pspice, the offset pins are connected to a potentiometer. And the third pin of the potentiometer is connected to 15V…
