LM258N

Product Summary

The LM258N is a dual operational amplifier. It 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 also is possible if the difference between the two supplies is 3V to 32V, and VCC is at least 1.5V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage. Applications of the LM258N 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, the LM258N can be operated directly from the standard 5-V supply used in digital systems and easily can provide the required interface electronics without additional ±5V supplies.
