Could you please tell me the operating temperature for the LM4755? It appears it's only available in one variant with part number LM4755TSX/NOPB. I see several locations where it's range is listed at -20 to 80 deg C, but on page 3 of the datasheet, it suggests it'll operate from -40 to +85 deg C. I see -20 to 80 deg C in more places, so I presume that's correct, but I wanted to know the official answer.
