The LM324AN is a low-power quad Operational Amplifiers consists of four independent, high gain, internally frequency compensated operational amplifiers designed to operate from a single power supply over a wide 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 include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems.
Eliminates need for dual supplies
Four internally compensated op amps in a single package
Allows direct sensing near GND and VOUT also goes to GND
Compatible with all forms of logic
Power drain suitable for battery operation
Unity gain cross frequency is temperature compensated
Input bias current is also temperature compensated
