LMC6492: Thermal Resistance

Part Number: LMC6492

Please provide the thermal resistance Rtheta_JC for the LMC6492BEMX. The Rheta JA is provided in the datasheet but not the Rtheta JC

The question was already asked / provided here:

But the answer was not posted in the forum - please reply within the e2e forum so this will be searchable in the future.

  • Hi Steve,
    I will turn in a thermal data request for LMC6492. Please allow 3-5 business days and I will get back to you. The forum post in your question (e2e.ti.com/.../795907) is referring to a different device.

    Best Regards,
