The LM358N/NOPB is a two independent, high gain, internally frequency compensated Operational Amplifier IC, designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. The LM358N/NOPB can be directly operated off of the standard 3.3V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.
