Dual op-amps for lowpower consumption
This circuit consists of two independent, high gain operational amplifiers (op amps)
that have frequency compensation implemented internally. They are designed
specifically for automotive and industrial control systems. The circuit operates 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.
Application areas include transducer amplifiers, DC gain blocks and all the
conventional op amp circuits which can now be more easily implemented in single
power supply systems. For example, these circuits can be directly supplied from
the standard 5 V which is used in logic systems and easily provides the required
electronic interfaces without requiring any additional power supply.
In linear mode, the input common-mode voltage range includes ground and the
output voltage can also swing to ground, even though operated from a single power
supply.

1. All voltage values, except differential voltage are with respect to network ground terminal.
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 short-circuits on all amplifiers.
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 an input diode clamp. In addition to this diode action, there is 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. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor in series with the inputs to limit
the input current to 400 µA max (R = (Vin - 32 V)/400 µA).
6. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
7. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of
the device. This is done for all couples of connected pin combinations while the other pins are floating.
8. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no
external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.

2. The direction of the input current is out of the IC. This current is essentially constant as long as the output is not saturated, so there is no
change in the loading charge on the input lines.
3. Due to the proximity of external components, ensure that the stray capacitance does not cause coupling between these external parts. This
can typically be detected at higher frequencies because this type of capacitance increases.

Macromodel
An accurate macromodel of the LM2904, LM2904A is available on STMicroelectronics’ web site at: www.st.com .
This model is a trade-off between accuracy and complexity (that is, time simulation) of the LM2904, LM2904A
operational amplifier. It emulates the nominal performances of a typical device within the specified operating
conditions mentioned in the datasheet. It also helps to validate a design approach and to select the right
operational amplifier, but it does not replace on-board measurements.
