•DC Gain Blocks

•Conventional OpAmp Circuits

3 Description

The LM124-N series consistsof four independent,

high-gain, internally frequency compensated

operational ampliers designed to operate from a

single power supply over awide range of voltages.

Operation from split-power supplies is also possible

and the low-power supply current drain is

independent of the magnitude of the power supply

voltage.

Application areas includetransducer ampliers, DC

gain blocks and all the conventional op amp circuits

which now can be more easily implemented in single

power supply systems. For example, the LM124-N

series can directlyoperate o ofthe standard 5-V

power supply voltagewhich is used indigital systems

and easilyprovides the requiredinterface electronics

without requiringthe additional±15 Vpower supplies.
