LM2902,LM324/LM324A,LM224/
LM224A
Quad Operational Amplifier
Features

Description

• Internally Frequency Compensated for Unity Gain
• Large DC Voltage Gain: 100dB
• Wide Power Supply Range:
LM224/LM224A, LM324/LM324A : 3V~32V (or ±1.5 ~
15V)
LM2902: 3V~26V (or ±1.5V ~ 13V)
• Input Common Mode Voltage Range Includes Ground
• Large Output Voltage Swing: 0Vto VCC -1.5V
• Power Drain Suitable for Battery Operation

The LM324/LM324A,LM2902,LM224/LM224A 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 twosupplies is 3 volts to 32 volts. 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.
