LTC2984 how access raw measurement value of RTD or Thermistor (rather than calculated temperature value)

JCheney on Jun 7, 2021

Is there an easy way to get the raw measurement value (uV) of an RTD or Thermistor so that I can calculate the resistance rather than temperature.

Jellenie,

Thank you. I believe that I have found an answer. In the demo code, there is a way to get both the Temperature and the Resistance value out of the IC. I see that the data can be retrieved from…

Jellenie,

Thank you. I believe that I have found an answer. In the demo code, there is a way to get both the Temperature and the Resistance value out of the IC. I see that the data can be retrieved from "reserved" memory addresses starting at 0x060.
