LM324/LM324A, LM2902/LM2902A
Quad Operational Amplifier
Features
• Internally Frequency Compensated for Unity Gain • Large DC Voltage Gain: 100dB • Wide Power Supply Range:
LM324/LM324A : 3V~32V (or ±1.
5 ~ 16V) LM2902/LM2902A: 3V~26V (or ±1.
5V ~ 13V) • Input Common Mode Voltage Range Includes Ground • Large Output Voltage Swing: 0V to VCC -1.
5V • Power Drain Suitable for Battery Operation
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 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.
