Now i am see the datasheet of AD9984A, at page 5 it say operating temperature is -20~85 . And the storage temperature is -65 ~150. But at last the page 42 the ORDERING GUIDE say the temperature range is 0~70? What does it mean? I want to use it work on at -15 degress. Does it will work on at -15 degress? Thankyou !
