Other Parts Discussed in Thread: LMT70, REF3430, CC2640, OPA376, REF3318, OPA192
Hi Guys,
I'm now working on a project measuring skin temperature .The sensor is LMT70 from TI. Base on human-body temperature(35℃~40℃) , the output voltage of LMT70 is about 0.8V-0.9V.
Through lots of experiment data, we found the ADC in controller has a small but fixed deviation, this deviation cause about 1℃ gap( unbearable :( ) between a actual temperature measured by
a much more precise thermometer .
So I need 2 reference voltage points to calibrate my controller's ADC. According to the application, I hope the voltage calibtared point is as close to 0.9V as possible. Hope helps from you.
Thanks .
