Drawing upon circuit designs refined for Quad Operational Amplifiers, these dual operational amplifiers showcase minimal power consumption, an extended common mode input voltage range reaching ground/VEE, and the ability to operate on either single or split supplies. The LM358 series is functionally equivalent to half of an LM324.
These amplifiers offer numerous advantages over conventional operational amplifier types in single supply scenarios. They can function with supply voltages as low as 3.0V or as high as 32V, boasting quiescent currents approximately one-fifth of those associated with the MC1741 (on a per-amplifier basis). The common mode input range encompasses the negative supply, thereby obviating the need for external biasing components in many applications. Additionally, the output voltage range includes the negative power supply voltage.
