HDC2080: Temp accuracy standard deviation across devices

Errol Leon6

Part Number: HDC2080


Hi team,

My customer is using HDC2080 in their design.  They are wondering if there is any more shareable information about the temperature accuracy across the -30 to +55 range... like what does 'typical' mean, stddev, limits, etc. There is the one chart in the data sheet and they are wondering if there is anything else.

Thank you in advance for your support!

    Hi Errol,

    We could not provide a maximum temperature accuracy specification for the HDC2080 outside of the range that is already given in the datasheet (5°C to 60°C). Though we do provide a typical specification for the HDC2080 across temperature in Figure 3 of the datasheet. That typical specification generally refers to the commonly observed temperature accuracy of our parts during characterization, and may not refer precisely to an integer multiple of the standard deviation (i.e. it may not be 1σ, 2σ, 3σ etc.).

    The maximum temperature accuracy is what we warranty all parts sold will fall into. Please note that we confirm the temperature accuracy of our parts inside a stirred liquid oil bath, versus a highly accurate RTD probe. This environment is stable enough to provide the most reliable results. 

    Best Regards,
