AFE for human body(skin) temperature measurement

K.Yaita

Other Parts Discussed in Thread: TMP112, LMT70

Hi Team,

My customer is looking for the solution for human body(skin) temperature measurement.
The constitution that he considers is the following.
*thermister(remote) - AMP - ADC - MCU

He is looking for ADC(AFE) that has the function of thermal compensation(correction).
He doesn't want MCU to compensate.

Is there any solution for TI?

Kensuke,

I don't know of a solution off hand. Have you looked at our sensor page? www.ti.com/.../what-are-you-sensing.page

Hello Yaita-san,

If the customer is okay with a one chip solution, our TMP112 is temp sensor with body temperature applications.

Hi Josh-san,

Thank you for your reply.
I will suggest TMP112(digital output) and LMT70(analog output) for the solution.

Hello Yaita San,

Just a warning, the LMT70 does not include an internal ADC so they will still have to deal with thermal compensation on the MCU or ADC. But it is a good part for skin temp sensing.
