This document describes the LM358, LM258, LM2904, LM2904A, LM2904V, NCV2904 and other models of single supply dual operational amplifiers. These amplifiers feature low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. They have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as 3.0V or as high as 32V, with quiescent currents about one-fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage.
