description/ordering information

This device consists of two independent, high-gain, frequency-compensated operational amplifiers designed

to operate from a single supply over a wide range of voltages. Operation from split supplies is possible as long

as the difference between the two supplies is 3 V to 26 V (3 V to 32 V for V-suffix devices), and V

is at least

1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the

magnitude of the supply voltage.

Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational

amplifier circuits that now can be implemented more easily in single-supply-voltage systems. For example,

these devices can be operated directly from the standard 5-V supply used in digital systems and easily provide

the required interface electronics without additional 5-V supplies.

The LM2904Q is manufactured to demanding automotive requirements.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential voltages and V

terminal.

specified for measurement of I , are with respect to the network ground

2. Differential voltages are at IN+ with respect to IN−.

3. Short circuits from outputs to V

can cause excessive heating and eventual destruction.

4. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable

ambient temperature is P = (T (max) − T )/θ . Operating at the absolute maximum T of 150°C can affect reliability.

5. The package thermal impedance is calculated in accordance with JESD 51-7.
