    Hi iehncent,

    The difference between the LMT70 and LMT70A is the matching feature in the LMT70A. The sensors are guaranteed to be matched within 0.1C of each other when picked from the tape and reel consecutively. The TAO output is a voltage output, it can fed directly into a multimeter or an input of an ADC. The value of an R and a C entirely depend on the design of the system including the type of ADC, sampling rate, noise, and other considerations.
