Part Number : LM324N
Function :Quad Operational Amplifier / Large DC Voltage Gain: 100dB / Large Output Voltage Swing: 0V to VCC -1.5V
Manufacturer : Fairchild Semiconductor
Pinout : 
Description
The LM324/LM324A, LM2902/LM2902A consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range.
Operation from split power supplies is also possible so long as the difference between the
two supplies is 3 volts to 32volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems.
