HDC1080: Typical RH value

Part Number: HDC1080

Hi

I have a question related with following thread.

The typical RH Accuracy vs. RH characteristics is shown in figure 2 of datasheet.

1.

Can we consider that the RH accuracy of all shipped devices can be within figure 2?

2.

If the device whose RH accuracy is out of figure 2, can we regards its device is defective?

BestRegards

    Dear Na

    1.
    RH accuracy specified in the datasheet is the typical value
    It means that most of the devices have accuracy like the one described in figure 2

    2.
    a. The accuracy in an application is strongly related to the application design. Condition like self heating, wrong placement in the PCB. I suggest to look at the HDC1080 application note

    b. For the reasons above, it's very difficult to imply a high RH accuracy to the HDC1080.
