LMT87: Application inquiry

Part Number: LMT87

Hello Team,

Good day.

My Customer would like to know if the LMT87 part will work for long-distance or not? Do they need an analog front end signal conditioning circuit for LMT87? what is the maximum wire length they can use?

Regards,

Renan

  • Hi Renan,

    LMT87 is specified to source/sink 50uA and a maximum output capacitance of 1100pF. This limits it's ability to drive a lot of cabling, or stabilize voltage level in the face of EMI. I would recommend using a buffer with the sensor. It may be fine for shorter distances without buffer, but I can't estimate a max length.

    Can you tell me more about the application? maybe there is another product that fits your needs.

    thanks,

    ren
