All characteristics are measured with zero common-mode input voltage, unless otherwise specified.
Full range (MIN to MAX) for LM2901 is –40°C to 125°C. All characteristics are measured with zero common-mode input voltage, unless
otherwise specified.
V
CC
MAX = 30 V for non-V devices, and 32 V for V-suffix devices
The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the common-
mode voltage range is V
CC+
– 1.5 V; however, one input can exceed V
CC
, and the comparator will provide a proper output state as long
as the other input remains in the common-mode range. Either or both inputs can go to V
CC
MAX without damage.
