Note 4:
For operating at high temperatures, the LM2902EP must be derated based on a +125C maximum junction temperature and a thermal resistance of 88C/W
which applies for the device soldered in a printed circuit board, operating in a still air ambient. The dissipation is the total of all four amplifiers—use external resistors,
where possible, to allow the amplifier to saturate of to reduce the power which is dissipated in the integrated circuit.
Note 5:
Short circuits from the output to V
+
can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output
current is approximately 40 mA independent of the magnitude of V
. At values of supply voltage in excess of +15V, continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
Note 6:
This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action
on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V
voltage level (or to ground for a large overdrive) for the time duration
that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value
greater than 0.3V (at 25C).
Note 7:
The LM2902EP specifications are limited to 40C
≤
T
A
≤
+85C.
Note 8:
"Testing and other quality control techniques are used to the extent deemed necessary to ensure product performance over the specified temperature
range. Product may not necessarily be tested across the full temperature range and all parameters may not necessarily be tested. In the absence of specific
PARAMETRIC testing, product performance is assured by characterization and/or design."

with V
+
from 5V to 26V; and over the full input common-mode range (0V to V
+
1.5V)
Note 10:
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.
Note 11:
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25C). The upper end of the
common-mode voltage range is V
1.5V (at 25C), but either or both inputs can go to +26V without damage, independent of the magnitude of V
.
Note 12:
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.
Note 13:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Note 15:
The LM124 within this data sheet’s graphics is referenced because of it’s a similarity to the LM2902, however is not offered in this data sheet.
