The LM2904W and LM2904AW circuits consist of
two independent, high gain operational amplifiers
which employ internal frequency compensation
and are designed specifically for automotive and
industrial control systems. They operate from a
single power supply over a wide range of
voltages. The low power supply drain is
independent of the magnitude of the power
supply voltage.

supply. In linear mode, the input common mode
voltage range includes ground. The output
voltage can also swing to ground even though
operated from a single power supply.
Application areas include transducer amplifiers,
DC gain blocks, and all the conventional op-amp
circuits which now can be more easily
implemented in single power supply systems. For
example, these circuits can be directly supplied
from standard +5 V which is used in logic systems
and easily provides the required interface
electronics without requiring any additional power

2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.

3. Short-circuits from the output to VCC can cause excessive heating if VCC+ > 15 V. The maximum output current is
approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers.
TI
VE
4. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP transistor becoming forward biased and thereby acting as input diode clamps. In addition to this
diode action, there is also NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the
Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven
negative. This is not destructive and normal output is restored for input voltages above -0.3 V.
5. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values.
6. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
IN
AC
7. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device
with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.
8. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to
the ground.

3. Due to the proximity of external components, ensure that stray capacitance does not cause coupling between these
external parts. Typically, this can be detected because this type of capacitance increases at higher frequencies.

Important note concerning this macromodel
IV
E
Please consider the following remarks before using these macromodels.
All models are a trade-off between accuracy and complexity (i.e. simulation time).
●
Macromodels are not a substitute to breadboarding; rather, they confirm the validity of
a design approach and help to select surrounding component values.
●
A macromodel emulates the nominal performance of a typical device within specified
operating conditions (for example, temperature, supply voltage). Thus the
macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the
main parameters of the product.
