  • OPA27: OPA27GU/2K5 MSL confirmation

    TI Thinks Resolved
    Part Number: OPA27 Kindly advise which is the correct MSL level for MPN# OPA27GU/2K5 as there is same MPN but two difference MSL show in TI website.

  • OPA27: Allowable max junction temperature

    TI Thinks Resolved
    Part Number: OPA27 What is the absolute max allowable junction temperature of OPA27GU?

  • OPA27: Thermal resistance information needed

    TI Thinks Resolved
    Part Number: OPA27 Can you please provide the thermal resistance values (Theta J-B and Theta J-C) for part OPA27 GU. Thank you.

  • RE: OP27: SPICE model to use in Altium

    Hey Michael, We offer spice models that can be found on the product page under Design & development > Design Tools & simulation. These work in Tina Ti and Pspice for Ti. I am unsure if you can use them directly in Altium but maybe there is a converter…

  • RE: OP07: amplifier which could adjust input offset voltage

    Great recommendation Clemens! Sirui, The OPA27 is p2p with OPA07 in the SOIC package and operates from -40C to 85C. Thanks, Zach

  • RE: Does TI have any integrated solutions for amplitude demodulation?

    Hi A, I wouldn't use an analog multiplier for this task. Have you noticed that the MPY634 has an input offset voltage that is about 1000 times higher than the offset voltage of OPA27? And, there's still the high price of MPY634 or AD630... Ka…

  • RE: Millivolt range AC to DC OP ?

    Resolved
    Hi Yordan, the OPA27 offers much lower DC errors, provided the feedback resistances are sufficiently low. So, there's no AC coupling necessary. Kai

  • RE: Power Supply Range for OPA27GU Precision Op-amp

    Jit, Since the power supply voltage range for OPA27 is from +/-4V to +/-22V (thus a total supply from 8V to 44V), it is pefectly fine to operate it on +28V single supply.
