HDC2010: Is Operating Temperature Range of HDC2010 –40°C to 125°C ?

K.N
Expert 4445 points
Part Number: HDC2010

Hello Team

There is following mention in DataSheet Page1 (1 Features) of the following URL.

URL:www.ti.com/.../snas693.pdf

• Temperature Range:
– Operating: –40°C to 85°C
– Functional: –40°C to 125°C


Please tell me the meaning of
" Temperature Range:　– Operating: –40°C to 85°C ".


I think that the description of –40°C to 85°C is unnecessary.
I think that the following description is correct.

• Operating Temperature Range:
 –40°C to 125°C

    Hi Nishijima-san,

    You are right. Section 6.5 Electrical Characteristics on HDC2010 Data sheets clearly states that the operating range for the temp sensor is -40C to 125C. We are updating the data sheet and will take your suggestion under consideration.

    Please notice foot note (11) on same section for the humidity sensor:
    Recommended humidity operating range is 20 to 80% RH (non-condensing) over 0 to 60°C. Prolonged operation beyond these ranges
    may result in a shift of sensor reading, with slow recovery time.

    Regards,
    Jose
