  • LMT85: Power supply and Output voltage relationship

    Resolved
    Part Number: LMT85 Hi, Power supply for LMT85 is rated for (+1.8V to +5.5V) and from the Transfer Table of the datasheet i can see the Vout at -50C is 1955mV~1.9V. Just trying to understand if I operate the device at 1.8V then also the Transfer table values…

  • RE: LM20: next gen of LM20

    Resolved
    Hello Given, The link below shows all analog sensors which support -40C to 150C and are available in SC70(DCK) 5 pin package. TMP9A00-EP is the only device with the same gain of -11.77mV/C. If you can use a different sensor gain, TMP235 is a good candidate…

  • LMT85: About Pin out of LMT84 / LMT85 / LMT86 / LMT87 (DCK package)

    TI Thinks Resolved
    Part Number: LMT85 hi, Is the correct functional behaviour of LMT85-Q1 impacted if inadvertently PIN5 has been connected to VDD instead of GND? if yes, to which extend? thanks, Ulrike
