1.4V, R
S
= 0Ω with V
+
from 5V to 30V; and over the full input common-mode range (0V to V
+
−
1.5V) for LM2902-N, V
+
from 5V to
26V.
The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the
state of the output so no loading change exists on the input lines.
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25°C). The
upper end of the common-mode voltage range is V
+
−
1.5V (at 25°C), but either or both inputs can go to +32V without damage (+26V
for LM2902-N), independent of the magnitude of V
+
.
Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This
typically can be detected as this type of capacitance increases at higher frequencies.
