Single Supply Quad Operational Amplifiers using LM324, Lm324A, LM224, LM2902, LM2902V, NCV2902

The LM324 series are low-cost, quad operational amplifiers with true differential inputs. They have several distinct advanteges over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.0V or as high 32V with quiescent currents about one-fifth of those assciated 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.

Short Circuited Protected Outputs
True Differential Input Stage
Single Supply Operation: 3.0V to 3.2V (LM224, LM324, LM324A)
Low Input Bias Currents: 100nA Maximum (LM324A)
Four Amplifiers Per Package
Internally Compensated
Common Mode Range Extends to Negative Supply
Industry Standard Pinouts
ESD Clamps on the Inputs Increase Ruggedness without Affecting Device Opertion
