LM2904WH General Description

This circuit consists of two independent, highgain, 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 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 will easily provide the required interface electronics without requiring any additional power supply.

1. 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.
2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
3. This input current only exists when the voltage values applied on the inputs is beyond the supply voltage
line limits. This is not destructive if the current does not exceed 5 mA as indicated, and normal output is
restored for input voltages above -0.3V.
4. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
5. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5). This is done for all couples of
connected pin combinations while the other pins are floating
6. 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.
