*Full range(MIN to MAX),for the AMS393 is 0℃ to 70 ℃.All characteristics are measured with zero
common-mode input voltage unless otherwise specified.
** The voltage at either input or common-mode should not be allowed to go negative by more than
0.3V.The upper end of the common-mode voltage range is Vcc-1.5V,but either or both inputs can go to
30V without damage.
