The LM358 contains two independent, high gain, internally frequency compensated operational amplifiers which have been designed to operate from a single power supply over a wide range of voltages. it can also operate from split power supplies and its low power supply current drain is independent of the power supply voltage.
Applications include sensor amplifiers, dc gain blocks and conventional op amp circuits which can be easily implemented in single power supply systems.
As an example, the LM358 can be operate directly from a standard +5V power supply voltage which is used in digital systems and will easily provide the necessary interface electronics without requiring the additional ±15V power supplies.
