Part Number: TMP112
Other Parts Discussed in Thread: HDC2010, , TMP117, TMP116

Hello,

I'm using HDC2010 as temp and humidity sensor but now, I'd like to switch to temp-only sensor.

I didn't find in your portfolio equivalent performances as temp sensor (accuracy/shutdown current/ mainly).

Any recommendation better than TMP112 ?

Thanks,

Hello Thomas

TMP117 is a newer part of the product family with best in class accuracy and 300 nA shutdown current.

Thank your for sugestion,

Still doesn't get the difference with HDC2010 (0.2°, 50nA shutdown, less than 1ms conversion time + humidity for 1$) vs TMP117 (0.1°, 150nA shutdown, 15ms conversion time for 1.85$) ? The current consumption while converting is a higher (0.6mA vs 0.2) but that's totaly fine for me.
I would love a non-opened HDC2010 (with no humidity sensor of course)

TMP116 is from the same family as TMP117, but has 0.2C accuracy. Even though the accuracy spec is similar, you may notice lower noise in the TMP116/7 than in HDC2010 due to differences in architecture. Additionally, HDC2010 is a DSBGA device which has the lowest possible packaging costs.

Thanks,
Ren
