Hi, i am planning on using TMP112 for temperature measurent, but i have a few questions.
The sensor will be measuring human body temperature coupled with a stainless steel. In order to themally couple the IC package should use the GND lead?Is there any way that i can thermally couple it but still keep it isolated?
Second question is about accuracy and power. The final device will be battery powered (CR2032 for instance). What is the best way to improve accuracy? Directly power from the battery (with the apropriate bypass capacitor) or use an LDO to get a more stable power rail? The reason of my question is that with lower voltage the sensor will decrease the accuracy, but i am afraid the slowing decreasing voltage of the battery will be worst.
Thank you!
