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 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 ...
