(1) All characteristics are measured with zero common-mode input voltage, unless otherwise specified.
(2) 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.
(3) V
MAX = 30 V for non-V devices, and 32 V for V-suffix devices
CC
(4) 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
– 1.5 V; however, one input can exceed V
CC+
state as long as the other input remains in the common-mode range. Either or both inputs can go to V
