Single Supply Quad Operational Amplifiers LM324, LM324A, LM324E, LM224, LM2902, LM2902E, LM2902V, NCV2902 The LM324 series are low cost, quad operational amplifiers with true differential inputs.
They have several distinct advantages over standard operational amplifier types in single supply applications.
The quad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one fifth of those associated with the MC1741 (on a per amplif
