The LM324 features four independent, high gain, internally frequency compensated operational amplifiers designed specifically to operate from a single rail power supply with voltages ranging from 3 - 32V.
Operation from dual rail power supplies is also possible and the low current drain is independent of the magnitude of the power supply voltage.
Uses include sensor amplifiers, DC gain blocks and conventional op amp circuits which can be easily run off asingle power supply system.
The LM324 can be run using the standard +5V power supply voltage which is used in digital systems and will provide the required interface electronics without needing additional ±15V power supplies.
