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 compen-
sated operational amplifiers which were designed spe-
cifically 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.
