Part Number:TMP007
I am working on a medical device that will use TI's TMP007 to measure blood temperature. The sensor itself will be at room temperature when the device is turned on, but will gradually warm up to the temperature of the blood. So the TMP007"object temperature" will vary from 35°C - 40°C, but the "die temperature" can vary between 20°C - 40°C. Within this range, I need an accuracy of ±1°C.
I am currently trying to calibrate the TMP007 using the TMP007EasyCal software. I can vary the "object temperature" using heated water and log the reference temperature, TMP007 die temperature, TMP007 object voltage every second. However, I'm not sure what combinations of die and object temperatures to use to obtain the best coefficients. What should I choose? Also, how much data should I record at each point?
Thank you,
