LMT70EVM: Ordering LMT70EVM to separate and use LMT70.

Tasneem Bas

Part Number: LMT70EVM
Other Parts Discussed in Thread: LMT70,

I am working on a biomedical engineering design project and i'm trying to collect accurate skin temperature values.

Can I order the LMT70EVM Evaluation Board then snap apart the LMT70 sensor and use it as a temperature sensor by connecting it directly to my controller unit (Adafruit feather or Raspberry Pi Zero)? and will it have the same accuracy as LMT70 (+-0.05)?

I am interested in doing this because i think i may have some issues with soldering the LMT70 to a PCB and i want to use it in measuring skin temperature from the palm of the hand.

    Hi Tasneen,
    Nothing prevents you to do use the breakout portion of the LMT70EVM and make the connections to the development platform of your preferences. The accuracy will be kept as long as the ADC and reference systems are comparable to the ones used in the EVM.
    Once you decide to design your own boards please refer to the application notes in the technical documents section on the LMT70 webpage. Link
    below.
