LMT70: LMT70 ADC Calculation

Kanimozhi Raju
Prodigy 115 points
Part Number: LMT70

I am using LMT70 for measuring skin tempeature and I am not using integerated ADC with mSP430.I am trying to interface with kinetis series.I have seen the equations used to calculate for tempearture like first order.I could not understand what to use for my code.Could you please me the equation to convert my analog input to digital output for my k53 controller .Thanks in advance.

    Kanimozhi,

    If not sure if I understand you correctly...
    The steps to determine the equation for your application can be found in the datasheet (pg. 12-13).
    The first order equation will be in the TM = m × VTAO + b form, where VTAO is the ADC voltage reading.
    We do not support kinetis but I'm sure you can find example codes for the kinetis ADC conversion online.
