LM2904, LM2904A
Low-power dual operational amplifier
Features
Internally frequency-compensated
Large DC voltage gain: 100 dB
Wide bandwidth (unity gain): 1.1 MHz
(temperature compensated)
Very low supply current/amplifier, essentially
independent of supply voltage
Low input bias current: 20 nA (temperature
compensated)
Low input offset current: 2 nA
Input common-mode voltage range includes
negative rail
Differential input voltage range equal to the
power supply voltage
Large output voltage swing 0 V to (VCC+ -1.5 V)
Description
This circuit consists of two independent, high
gain, internally frequency-compensated
operational amplifiers designed specifically for
automotive and industrial control systems. It
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
interface electronics without requiring any
additional power supply.
In the 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 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.
9. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly
to the ground through only one pin. This is done for all pins.

1. VO = 1.4 V, RS = 0 Ω, 5 V < VCC+ < 30 V, 0 V < Vic < VCC+ - 1.5 V.
2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output,
so there is no change in the loading charge on the input lines.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V.
The upper end of the common-mode voltage range is VCC+ –1.5 V, but either or both inputs can go to +32 V without
damage.
4. 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.

4 Macromodel
An accurate macromodel of the LM2904 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 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.
