DESCRIPTION/ORDERING INFORMATION

The LM258A 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 3 V to 30 V, and VCC 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, this device can

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

interface electronics without additional ±5-V supplies.
