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.
