LM124/LM224/LM324/LM2902 Low Power Quad Operational Amplifiers
August 2000

Low Power Quad Operational Amplifiers
General Description Advantages
The LM124 series consists of four independent, high gain, n Eliminates need for dual supplies
internally frequency compensated operational amplifiers n Four internally compensated op amps in a single
which were designed specifically to operate from a single package
power supply over a wide range of voltages. Operation from n Allows directly sensing near GND and VOUT also goes
split power supplies is also possible and the low power to GND
supply current drain is independent of the magnitude of the n Compatible with all forms of logic
power supply voltage. n Power drain suitable for battery operation
Application areas include transducer amplifiers, DC gain
blocks and all the conventional op amp circuits which now Features
can be more easily implemented in single power supply
systems. For example, the LM124 series can be directly n Internally frequency compensated for unity gain
operated off of the standard +5V power supply voltage which n Large DC voltage gain 100 dB
is used in digital systems and will easily provide the required n Wide bandwidth (unity gain) 1 MHz
interface electronics without requiring the additional
